Trek alpha sizing for MTB – what is it?

The old-school approach of measuring the frame size of Trek bikes is a thing of the past. With newer inventions and modern bike geometry, alpha sizing is used in place of numeric sizing on Trek mountain bikes.

Why is alpha sizing important?

1. Easier approach

Instead of using size numbers like 19.5, the sizes can be classified into S, M, ML, L, XL, and XXL. So, someone with a 17.5 size can go for the medium and a 19.5 is a large size. You don’t have to keep a tab on numbers; instead, the alphabet makes it easier.

2. Measurement based on reach

In earlier times the frame size measurement of Trek bikes was solely based on seat tube length. Things have changed, and modern mountain bike geometry focuses more on reach as of now. Hence, alpha sizing measures what matters and is a more simplified way of measuring bike size.

Trek sizing – virtual vs actual

This can puzzle you a bit as they both are somewhat similar yet there is a subtle difference. Actual size can be termed as the overall length of the seat tube from the center of the bottom bracket to the center of the top tube intersection with the centerline of the seat tube.

On the other hand, virtual sizing is the overall length of the seat tube ranging from the center of the bottom bracket to the mid-point of the imaginary horizontal top tube in which it connects with the seat tube.

If I had to give you an example, a bike might have a virtual size of 18.5 and an actual size of 17.5. This means that the bike size feels like 18.5, but in actual sense, the frame size is 17.5. It doesn’t make much of a difference as it is there only to let you know what it is (actual size) and what it looks like in size (virtual size).

People also ask

Trek 17.5 frame size – what does it mean.

A 17.5 frame size is considered an M size (Medium) in terms of alpha sizing. Any individual who is 161-172 cm or a height of 5’3.4”-5’7.7” . If you are within this height range, going for a medium size shall be the right choice.

Trek medium frame size is for what height?

A medium size frame size (17.5) is ideal for a person with a height between 5’3.4”-5’7.7 ”. In centimeters, it is ideal for those around 161 to 172 cm in height.

Trek 24-inch bike is for what age?

When it comes to children, their bikes are measured in terms of wheel size instead of the standard frame size. These kid’s bikes have a size range between 12-26 inches, depending upon the height of the kid.

As far as a 24-inch wheel size is concerned, any kid between the ages of 8-11 can go for a fun ride with it. Some of the popular 24-inch bike models are Trek Roscoe 25, Wahoo 24, Trek Precaliber 24 , etc.

Trek 26-inch bike is for what height?

A 26-inch wheel-size bike is for kids with a height of 4’9”-5’3” (146-160 cm) . Wahoo 26 is a prime example of a bike in this category.

Trek 20-inch bike is for what age?

Trek 20-inch bikes are for children between 5 to 8 years of age. Additionally, if they are within the height of 3’9”-4’6” , it should be suitable for them.

Are Trek bikes good?

Trek bikes are considered to be extremely good and solid in build. It is known to be the number 1 performance bike brand all over the globe. Having its humble beginning in the year 1976 in Waterloo, Wisconsin, it has turned into the largest bicycle manufacturer all over the world. With an array of bikes ranging from, mountain, road, electric, and kids bikes, there is a lot to choose from a mammoth list.

How much is a used Trek bike worth?

It depends on a lot of factors in terms of how old the bike is, the year of production, which model, and a lot more. However, it can be within $1000-10,000 (depending on the model and other factors) .

Where are Trek bikes made?

The majority of their bikes are manufactured in Taiwan, China, Netherlands, and Germany too.

Why are Trek bikes so expensive?

Usually, the bike brand prefers top-tier components, suspensions, and frames that are ahead of its competitors. This results in additional costs that can be seen in the price tag and also many top-end Trek bikes are custom-made with less production, leading to being more expensive.

Trek bikes are a class apart in many ways with a range of bikes on offer for its fans across the world. Choosing the right size for you can be tricky, but this is where the Trek frame size chart comes to the rescue.

Trek as a bicycle brand might be on the costly side, but they punch above its weight to provide top-class bikes for the masses. I am always someone who roots for quality, and Trek provides what I need.

One comment

Thanks for your informative post. I really like the Trek alpha sizing for MTB because Trek frame sizes use alpha sizing rather than the usual inches or centimeters (cm), and they usually have a certain range of measurements.

Mountain Bike Size Chart & Fit Guide

Use this guide on mountain bike sizing to determine the right size bike for you. No matter your height and riding style, there’s a perfect fitting mountain bike out there for everyone. Don’t know which size bike you need? Take a look at our mountain bike size chart below to find out your frame size.

Keep reading to learn about mountain bike geometry and what to do if you are stuck between two sizes. There are so many bike shapes, sizes, and designs available, so head over to our catalog to shop all mountain bikes.

Mountain Bike Size Chart How To Size MTBs Wheel Size Geometry & Sizing

Mountain bike size chart

This chart is a great starting point, but isn’t always the definitive answer due to varying frame geometry and riders having unique proportions. Feel free to swing by our locations to test ride a mountain bike and know for sure. Keep reading to learn about other factors that go into choosing the right mountain bike size.

What is the right size bike for me?

Rider height is the main factor when it comes to finding your correct size. The best place to start is a mountain bike size chart. Check our helpful size chart above or look at model-specific charts published by a manufacturer on their website.

But sometimes the single data point of rider height can’t provide all the answers. If you fall between suggested chart sizes or want to double-check that you’ve got the perfect fit, there are additional metrics to help you decide:

Choose by skill level

More skilled riders can handle larger frames and take advantage of the increased stability while descending at high speeds, but a new rider may find that sizing up gives them "more bike" than they can comfortable control.

Choose by riding style

If you favor an aggressive riding position and a more stable feel, choose a larger frame for a longer wheelbase and roomier cockpit. If you prefer nimble handling and a more relaxed position, you can choose a smaller size.

Choose by wheel size

Most models share the same wheel size across the various frame options, but some brands put smaller wheels on their XS or S frames. Large 29” wheels are appropriate for all adults, but smaller riders might find them a bit unwieldy.

Choose by frame geometry

Every frame is different, so it’s important to test ride a few models to get a real feel of how they match your body and riding style. Later in this guide, we’ll break down the most important elements of frame geometry and what to look out for.

Mountain bike wheel size

The main wheel sizes available on mountain bikes are 26”, 27.5” and 29”. Choosing the right wheel diameter for you can help narrow down your search and help you find the perfect bike to fit your needs.

While the old standard for mountain bikes was 26”, the cycling world has embraced larger wheels because of their improved traction and ability to roll over obstacles. Bigger wheels will roll easier over obstacles than smaller wheels and can maintain higher speeds on rough terrain. 

Fast downhill bikes almost always come with 29” wheels. Large wheels also have a larger contact patch, meaning more rubber touches the ground to boost traction. Bigger isn’t always better, though. The medium 27.5” wheel size is ideal for riders nimble handling for better agility.

trek mtb bike size chart

What height is a 29 inch bike for?

Any adult can ride a mountain bike with 29” wheels, but 29ers are the ideal choice for taller riders over 5’7”. The large diameter wheels can feel a bit unwieldy or bulky for shorter riders or riders who aren’t as confident on the trails. Many brands put 29ers on larger frame sizes and 27.5” wheels on small frames to offer a consistent bike fit.

More on 29 inch mountain bikes

The bigger diameter of 29” wheels allows them to reach higher top speeds, roll over large obstacles, and increase stability. Larger wheels have a smaller angle of attack when they come in contact with a rock or root out on the trail and can more easily roll over obstacles. 29ers are the go-to size for downhill mountain bike races where riders need to maintain high speeds over rough terrain.

The larger contact patch of a 29” wheel also means more traction and grip, but not necessarily while cornering. The disadvantage of big wheels is that they can be less agile and responsive while turning or executing quick maneuvers. Check out our catalog and shop 29 inch mountain bikes.

trek mtb bike size chart

What height is a 27.5 inch bike for?

27.5 inch bikes are suitable for adults between 5’2” and 5’10”. That said, adults of all heights can ride this wheel size. Some brands claim that 27.5” wheels are especially useful for riders 5’7” and under.

More on 27.5 inch mountain bikes

Bike manufacturers like Trek and Giant have realized that matching smaller wheels to smaller frames can make for a better overall fit. Trek’s Smart Wheel Size approach pairs 29” wheels with M, L, and XL frames and puts 27.5” wheels on XS and S frame sizes.

27.5” wheels are more agile and responsive on technical terrain when compared to their 29” counterparts. They are big enough to roll over obstacles better than 26” wheels and small enough to provide nimble handling. As long as you’re not doing intense downhill riding, 27.5” wheels are the ‘goldilocks’ middle wheel size compatible with most terrain and rider heights.

trek mtb bike size chart

What height is a 26-inch mountain bike for?

A 26” mountain bike is the ideal set-up for younger riders or shorter adults who are between 4’10” and 5’5”. This smaller size is also great for riders that are not as confident on the trails. The smaller diameter 26” wheels are more agile out on the trails and are easier for shorter riders to maneuver over tricky terrain.

More on 26 inch mountain bikes

26” is the most common mountain bike wheel size on old school bikes, many of which are still around today. If you are on the hunt for a retro bike or are fixing up that bike in the garage, odds are it’s paired with a 26” wheelset. Remember that back in the day almost all mountain bikers regardless of height rode bikes with 26” wheels, so if that’s what works for you, feel free to buck the current trend of larger rims.

Bikes designed for dirt jumping utilize 26” wheels with strong alloy rims to handle landings after getting some serious air. Smaller wheels are stronger because they have shorter spokes, making the link between hub and rim less vulnerable to deforming under stress.

Large kids bikes utilize 26” wheels as the last step before tweens are ready to make the jump to adult sized bikes. Kids can continue to build up their riding confidence and skills on 26” wheels and switch later on to bigger mountain bikes.

Is it better to size up or down on a mountain bike?

Size up if…  you are a skilled rider or prioritize stability on fast descents.

Choose the smaller size if … you are a less aggressive rider or desire a more upright riding position and nimble bike handling.

If you find yourself between sizes on mountain bike size charts, additional metrics and rider preferences can help you figure out your perfect size. Bike size charts are simply suggestions and are often based on a single height measurement, so they fall short of telling the whole bike fit story. Follow this advice to pick the correct size when you’re right on the edge of two frame sizes.

trek mtb bike size chart

When to size up on a mountain bike

Going a size up means a longer bike with more space between the pedals and handlebars and bigger range of motion when standing up on the pedals. 

This extended set up is best for riders with relatively long torsos or who are flexible enough to handle the longer reach. 

Bigger bikes will naturally have a slightly longer wheelbase. Wheels farther apart means the bike will be more stable at high speeds and feel hefty rather than nimble on technical trails.

trek mtb bike size chart

When to size down on a mountain bike

Sizing down is the right option for people that want a more relaxed, comfortable riding position or like agile and responsive bike handling.

Smaller frame sizes have a shorter reach so the handlebars are closer to the seat, placing the rider in a more upright position. This is ideal for less flexible riders or riders with relatively long legs compared to their torso. 

The slightly shorter wheelbase provides a more nimble and zippy ride feel. As a less aggressive set-up overall, a smaller frame is the right choice for beginner to intermediate riders.

How mountain bike geometry affects bike size and fit

The overall shape and geometry of a mountain bike is composed of many specific measurements beyond just the frame’s size. Some of the most important measurements to pay attention to when it comes to size are reach, wheelbase, standover height, and stack. These dimensions make a big difference to how a bike will fit your body and perform on certain terrain.

There can be a little bit of number crunching when it comes to frame geometry, but understanding these metrics is key to getting the most out of your bike. There’s plenty to geek out on but don’t worry, we won’t go too far down the rabbit hole.

trek mtb bike size chart

Reach on a mountain bike frame is the horizontal distance between the bottom bracket and the center of the head tube. Basically it tells how much room there is between where your feet go and where your hands go on the bike and how much range of motion the rider has while pedaling.

Reach determines how far riders need to lean forward to grab the handlebars while standing on the pedals. MTB riders are frequently standing out of the saddle on descents or while climbing steep sections. Riders need sufficient room to maneuver on technical terrain, but not so much that they are too stretched out. Reach is the most important metric to pay attention to because it changes the between frame sizes.

Too much reach and you’ll be leaning too far forward while in the normal riding position. Short reach means the handlebars are relatively close to your body— riders can feel overly upright with not enough weight over the bottom bracket to pedal efficiently.

trek mtb bike size chart

Standover height relates to how high the top tube is when you are straddling the bike with your feet on the ground. It’s like when you stop at a stop sign and hop off the saddle to stand over your bike frame— there should be at least 2” of clearance between the top tube and your groin.

Standover height is more important for road bikes than it is on modern mountain bikes. MTB frame designs today have quite low standover heights, so it’s never a worry that it’ll be difficult to swing your leg over the frame to mount the bike or that you won’t be able to comfortably straddle the frame. That said, always check you have enough clearance to allow for quick and safe dismounts.

trek mtb bike size chart

Wheelbase & Chainstay Length

Wheelbase is the horizontal distance between the front and rear axles on a mountain bike. How far apart the wheels are is a major factor that determines whether a bike feels more stable or more nimble.

A longer wheelbase is more stable and is easier to control at high speeds, useful for steep descents or fast trails. Shorter wheelbases means the bike is a bit more compact and will be more maneuverable on technical terrain and around tricky obstacles.

Since wheelbase is essentially a measurement of the frame from one end to the other, wheelbase is made up of other metrics like reach, head tube, angle, and chainstay length added together. It’s important to recognize where the extra length (or lack thereof) is coming from to understand how the overall bike will feel out on the trails. 

Chainstay length, or rear center, is another measurement to look at. Chainstays connect the bottom bracket to the rear axle, and longer chainstays provide more stability at speed, while shorter ones feel more nimble. Some models utilize the same chainstay lengths across the size range, but not all.

trek mtb bike size chart

Stack is the vertical distance between the bottom bracket and the center of the head tube and determines how a bike will feel while pedaling in the saddle. While still an important metric to consider, stack doesn’t change as much as reach does between frame sizes. 

Stack gives riders a clue on how high up the handlebars will be relative to the pedals. If stack height feels too high or low, it can be adjusted with headset spacers or handlebar rise to fit the specific rider.

Mountain Bike Size FAQs

Why do some mountain bike frames use inches for sizing.

How to size a mountain bike has changed and bikes today are categorized according to alpha sizing (think: S, M, L, XL) rather than the length of the seat tube. 

Traditionally, frame sizes were listed in inches, but modern mountain bike designs with their low standover height and diverse geometries prevent seat tube length from being a representative measurement. Bike brands have realized that “size S” is much more intuitive for customers than listing a frame as “15 inches”. 

Many bike manufacturers have moved away from gender-specific designs and, instead, offer their bikes in a variety of sizes to fit any rider. For that reason, most brands don’t provide a women’s mountain bike size chart. The mountain bike frame size chart above works well for all types of riders regardless of gender or height.

What size mountain bike should I get for my height?

Riders under 5’5” fit best on either S or XS mountain bike frames, depending on which of those sizes are available. If you are between 5’6” and 5’10”, choose a size M. Riders 5’11” and taller should get an L or XL frame. Check out our mountain bike size chart for an exact recommendation.

What size mountain bike do I need if I'm 6 feet tall?

Riders that measure 6’ tall should ride a size L mountain bike frame. Some bikes use seat tube length instead of alpha sizing to measure their size. Look for a frame size marked between 19” to 20”.

How do you size a mountain bike?

Modern mountain bikes use alpha sizing to categorize frames as XS, S, M, L, or XL. Older mountain bikes used seat tube length, or the vertical distance from the bottom bracket up to the seat post clamp. Check out our mountain bike size chart or the sizing tools on a brand’s website to determine the correct size for you.

How do you measure yourself for a mountain bike?

The most important measurement to take is rider height. Take an updated measurement of your height (or have a friend help you) and compare it to our mountain bike size chart to find out which frame size works best for you.

What size is a medium mountain bike?

A medium mountain bike typically has a frame size of between 16” to 18”. Medium bike frames can fit riders between 5’6” and 5’10”.

Is a 19 bike frame a large?

A 19” bike frame is typically rated as a large frame, appropriate for riders between 5’10 and 6’2”. Depending on the manufacturer and specific model, large bikes can have frames that measure 19”, 19.5”, or 20”.

Is my mountain bike too small?

Feeling cramped, high knees while pedaling, and sitting too upright can be signs that your bike is too small. The reach, or horizontal distance from the bottom bracket to the center of the head tube, should be long enough that you can have a good range of motion both in and out of the saddle.

The Trek bike size chart, taking into account both height and inseam measurements, offers cyclists a comprehensive guide to selecting the perfect bike size for their body proportions. By considering both of these factors, riders can ensure an optimal fit and maximize their comfort and performance on the bike. Height and inseam helps determine the frame size. This chart enables cyclists to find the ideal frame size, for a comfortable riding position. With the Trek bike size chart by height and inseam chart, cyclists can confidently choose a bike that suits their body measurements and enhances their cycling experience.

Most important difference in mtb frames is the frame full suspension or hardtail. Trek offers bikes from both categories and have even more mtb bike types to offer.

Trek Road Bike Sizing

Trek road bicycles are being made in four different categories, depending on the riders needs. Aero road bikes have excellent aerodynamics and they are the choice for riders who are looking for speed and performance. Lightweight road bikes are excellent climbers and all-around bicycles. Endurance road bikes are built for those riders who spend a lot of time in the saddle, their intended use is to make riders as much as comfortable as possible during the long hours of riding. Gravel road bikes are for use on gravel and dirt roads.

Hybrid, as name states, brings a mixture of a road bike and mountain bike. They tend to have narrower tires than mountain bike and usually they have a front suspension (but sometimes comes with rigid fork too). Hybrid frames falls into the specific category between road and mtb bikes. They never come with drop bar, which differs them from road bicycles. They are ok choice for commuting and excellent one for casual fitness riders.

City bikes, as their name say, are intended for urban use on paved, asphalted roads. Main use is for transport and not for recreational riding.

Bike Size Chart: How to Choose the Right Bike Size? (GUIDE + Calculator)

Profile picture of Petr Minarik - the founder of cyclistshub.com

This guide will teach you how to choose the right bike size using bike size charts and other methods. It covers the most popular bike types, including hybrids/city, mountain, and road bikes .

Use this interactive calculator that recommends a bike size based on your inseam length and bike type. Alternatively, choose the bike size based on one of the three methods explained below .

Bike Size Calculator

DISCLAIMER: Please remember that the calculator does not consider your height, which may affect your bike size.

What Bike Size Do I Need?

To determine which bike size you need, use one of the following methods, sorted from the simplest to the most complex. Remember that simpler methods are less precise, while more complex methods offer greater accuracy.

Method #1: Bike Size Based on Your Height (The Easiest Method)

This is the easiest and quickest method to select a bike size. All you have to do is compare your height with the general bike sizing chart below .

However, this method doesn’t consider the type of bike, so it may not be as accurate as the methods below. As a result, the bicycle may not fit you perfectly.

Method #2: Bike Size Based on Your Inseam Length and Bike Size Chart

This is probably the best bike sizing method for most people. It is based on measuring your inseam length at home and comparing it with a bike size chart .

Once you measure the inseam length, use it to select the bike size. Most bicycle manufacturers use seat tube length and other details, including the standover height, in their bike size charts.

The standover height is the distance from the ground to the top of the top tube.

An illustration of a bike size based on the seat tube length and the standover height

If your inseam length is shorter than the standover height, the bike is too big for you.

The clearance, which is the difference between your inseam length and the standover height, should be around 1 to 2 inches.

This clearance is essential to prevent injuries caused by sudden or emergency stops.

IMPORTANT NOTES

  • The inseam length for choosing a bike size is measured differently from that used for buying pants. Learn more
  • To choose the most accurate bike size, always compare your measurements with the manufacturer’s bike size chart for your bike type.

Hybrid Bike Size Chart

Depending on the manufacturer, hybrid bikes usually come in descriptive sizes (XS-XL) and heights. However, you may still encounter all three types of size designations – in, cm, and descriptive sizes.

And here is a helpful infographic:

Hybrid bike size chart: Choose the hybrid bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in descriptive sizes (XS-XL).

Mountain Bike Size Chart

The size of mountain bikes is typically measured in inches (13″, 19″, etc.) or descriptive sizes (XS-XL).

Generally, smaller mountain bikes usually come with 27.5″ wheels, while larger ones have 29″ wheels.

And here are the sizes in the picture:

Mountain bike size chart: Choose the mountain bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in descriptive sizes (XS-XL).

Road Bike Size Chart

Road bike sizes are usually given in centimeters or descriptive sizes.

You should take extra care when choosing the size of your road bike. Road cycling is a discipline in which you spend long hours in the saddle, so selecting the right bike size is crucial.

It’s also essential to choose the right type of geometry. For instance, endurance geometry road bikes (where you sit more upright) are suitable for beginners, while aggressive (sporty/performance) geometry requires a certain amount of flexibility.

The following road bike size chart also applies to cyclocross and gravel bikes .

And again, an infographic:

Road bike size chart: Choose the road bike size based on your height and inseam length. This image includes table with height and inseam ranges (in inches and centimeters) and corresponding bike size in centimeters.

Method #3: Calculating the Bike Size

As we know from Method #2 , bike size is determined by the length of the seat tube. To effectively use this method, you must know the length of your inseam ( learn how to measure it correctly ).

To calculate the size of your next bike, use the following formulas depending on the type of bike you want to buy.

To calculate the size of your next bike, use the following formulas depending on the type of bike you want to buy. ( Source )

  • Inseam Length (cm) × 0.685 = Hybrid Bike Size (cm)
  • Inseam Length (cm) × 0.225 = MTB Bike Size (inches)
  • Inseam Length (cm) × 0.665 = Road Bike Size (cm)

1 in = 2.54 cm 1 cm = 0.39 in

After you receive the result, round it up to the nearest whole number. This will match the bike size charts above with a slight deviation.

Example of calculating the MTB Bike Size:

Your inseam length is 33 inches, and you want to buy a new mountain bike. Let’s do the math:

Convert cm to inches: 33 inches × 2.54 = 83.8 cm Calculate the bike size: 83.8 cm × 0.225 = 18.8 ≐ 19 inches

The size of your new mountain bike should be 19 inches .

Example of Calculating the Road Bike Size:

Your inseam length is 70 cm, and you want to buy a new road bike:

70 cm × 0.665 = 46.55 cm ≐ 47 cm

As you can see, your new road bike size should be 47 cm .

How to Measure the Inseam Length?

To measure your inseam length, follow these five simple steps or watch the video below:

  • Prepare a 0.75 to 1-inch (1.9-2.5cm) thick book and a tape measure.
  • Take off your shoes and stand with your back to the wall.
  • Put the book in your inseam, firmly pull it up, and hold it with your tights. Make sure the book is pressed against the wall on one side.
  • Measure the length from the top of the book to the floor.
  • Take the measurement.

NOTE : The inseam for choosing the right bike size is different (a few inches longer) from the inseam used to choose the pants’ size. Remember that inaccurate inseam length may affect the recommended bike size.

How to Measure Your Inseam for a Bicycle

Once you measure your inseam length (and eventually also your height), you can compare it with the bike size chart of the specific bike type. Based on it, you can choose the correct size.

Choosing the correct bike size is easy when you know how to do it. You can use the bike size calculator that recommends a size based on your inseam length and bike type, or try one of the three methods I explain:

  • The first method is simple but not very accurate. You only need to know your height and compare it with the universal bike size chart.
  • The second method is the most accurate. First, measure your inseam length and decide what bike type you want. Then, compare your inseam length with the hybrid, MTB, or road bike size chart, and you’ll have the right size to buy.
  • The third method requires some math but is more accurate than the first. You need to know your inseam length and use special formulas to calculate the size of your next hybrid, mountain, or road bike.

If you’re still unsure about what size bike to choose, please ask in the comments below or email me .

Choosing a Bike Size FAQ

I remember trying to choose the size for my first road bike. I asked a cycling forum for advice because I was stuck between two sizes. The forum members gave me some tips, but most were too complicated for a beginner like me. They suggested that I check the bike’s geometry, but I had no idea how to do that or compare it to my body measurements. So I asked my friend, who has been selling bikes for over 10 years at a local bike shop. He gave me the following advice: “It depends on what kind of rider you are. If you’re a recreational rider, go for a bigger frame. It’s more comfortable because you won’t have to raise the saddle as high as you would with a smaller frame. This will give you a more upright position, which is more comfortable. However, if you’re serious about cycling and want to race, a smaller frame will give you a more aerodynamic and aggressive position. Smaller frames are also more agile and lighter.”

There are several ways to choose the right size bike, but in this guide, I’ll explain three methods: 1. The first method is based on your height and a universal bike size chart. It’s the simplest but not the most accurate method. 2. The second method uses your inseam length and specific bike size charts for hybrid, mountain, and road bikes. It’s the most accurate method for most people. 3. The third method involves calculating the bike size using your inseam length and a unique coefficient that varies based on the bike type. It’s more accurate than the first method but not as accurate as the second. You can also use an interactive calculator that recommends bike size based on your inseam length. I recommend reading the entire article to better understand each method and decide which one works best for you.

Choosing the right bike size is crucial, not only for your comfort but also for preventing health problems. If your bike doesn’t fit you properly, you may experience pain in various body parts, such as your lower back, neck, and hands. ( Source ) According to Physio-pedia.com , there are four essential components of a good bike fit: correct foot position, saddle height, stem length, and handlebar position. However, remember that if your bike is two sizes too small or too big, you won’t be able to achieve a proper bike fit. Therefore, learning how to choose the correct bike size is important. You can avoid discomfort and potential health issues by selecting the right bike size. So, take the time to find the perfect fit for you.

If you have ordered a new bike the wrong size, I recommend returning it as soon as possible. Most online retailers allow returns. If you ride the wrong size bike, you risk injuring yourself (e.g., overloading certain muscles) or not being comfortable in the saddle. It also happens that even experienced cyclists ride the wrong size bike, so they often fail to adjust it to their liking.

It’s a bit complicated. The answer is mostly no, but there are some exceptions. Let me explain. Many people ask this question. But it is a wrongly asked question because bike size doesn’t depend on age. Our heights vary greatly, so a 19-inch bike may suit someone even if they’re not the “correct age” for it. The correct question is: “What height and inseam length is a 19-inch bike for?” With this information and the bike chart for the specific bike, you can determine who the bike is suitable for. Read the entire guide on choosing the right bike size for more information.

A 26-inch bike refers to a bicycle that uses 26-inch wheels. These wheels are commonly found on kids’ bikes, but some adult (mountain) bikes also use them. Nowadays, 27.5-inch and 29-inch mountain bikes are becoming more popular because they offer better comfort and speed. If you’re shorter than 5’0″ (150 cm), a 26-inch bike may be a good choice. However, if you’re taller, I recommend choosing a bike with at least 27.5-inch wheels. Check out this guide to learn more about selecting the right bike size.

Bike Sizing Guide: What Size Trek Bike Do I Need?

Written by  Gary Johnson / Fact checked by  Henry Speciale

what size trek bike do i need

Are you looking for a bike to buy and asking yourself “what size Trek bike do I need?”

Trek bike sizing is very straightforward and varies by type.

For example, mountain bikes follow a unique method called alpha sizing that uses designations such as small, medium, or large. Using this system, a 5’3” to 5’7” tall person can use a 17.5” frame size.

On the other hand, Trek road bike sizing takes into account the inseam length.

If you want to get on the road or hit that trail with your ideal two-wheeler, check out our sizing guides below.

trek-bike-size-chart

Trek bikes are comfortable and easy to ride, making them excellent for beginners. They also come in different dimensions, so you should find one that fits you perfectly.

Whether in inches or cm, our Trek bike size chart will help you match your height with the appropriate vehicle.

trek-moutain-bike-size-chart

Unlike other brands, Trek bikes have upgraded their MTB sizing with alpha classifications to remove guesswork for customers.

You may find that your chosen model has some and not all of the sizes in this Trek MTB size chart. In that case, branch out and look for XS and XXL options if the Trek M/L frame size doesn’t fit you.

Note that the women’s bike size chart also uses the alpha sizing guide for their line of women’s mountain bikes though the height requirement is slightly different for each size.

Did You Know

The Trek Marlin 5, which is a popular trail mountain bike, uses the alpha sizing chart, but its size is not limited to XS – XXL only! Trek also offers an XXS with 26” wheels for this MTB type.

Trek has given us 4 categories when it comes to road bicycles. These include:

  • Aero – The best aerodynamics for speed and performance
  • Endurance – Provides comfort perfect for long hours of riding
  • Time Trial – Speed-focused bikes with unique designs
  • Climbing – Lightweight bikes excellent for uphill climbing

Designed to be a mixture of road and mountain bikes, Trek hybrid bicycles are best used for casual rides and commutes.

What size bike should I get? What does “size” really mean? And what is the best way to find the correct model for yourself?

There are usually FOUR different aspects that you must consider and have a good idea about.

Riding Style

trek-bike-sizing

Do you want to ride your bike for fun or use it for racing and exhibition? Regardless of your budget, it is important that you consider the type of biking you want to do. Some people prefer to ride in the city, while others prefer to cycle off-road.

Trek bikes come in various sizes depending on the vehicle’s discipline, since some frames have different geometry to provide the support their riders need.

Rider Height

trek-frame-size-chart

Most bicycle models come in different sizes for different body types so that they fit most people well.

The height of a person, when measured from head to toe, can help determine the bike size that would match them. This is because taller people have longer upper and lower extremities compared to shorter people, which means they will need different sizes of bikes in order to ride comfortably.

Inseam Length

trek-marlin-5

After careful deliberation with the above two factors, the frame size is then ultimately determined by your inseams or the distance from your crotch to the bottom of your leg.

You should take this into consideration because it will determine how much room there is between your feet and handlebars when sitting on the saddle comfortably.

Practical Use /Test Ride

trek-mountain-bike

Last but not least, once you have chosen your bicycle size and Trek model, test out the bike with at least a short ride. This will let you assess the balance and comfort of the chosen vehicle.

Whether you ride recreationally or professionally, you cannot choose blindly. First, bikes are expensive, and second, you must buy the correct product to use it for a long time.

trek-road-bike

If you’re done with our Trek frame size chart, Trek’s online website also has a unique feature that helps you select the correct frame size. You can try their bike finder, which asks for your riding style, height, and even inseams before arriving at a recommendation.

In case you haven’t noticed, there is a lot of variation in bicycle sizing, and looking for the size I need for my height was not a walk in the park.

Well, I hope our guide answered your question about what size Trek bike do I need. Should you have any more questions, send us a message.

Bespoken Word – Trek is slashing the number of bikes it offers by 40%. Here's what that means for your favorite brands in the future

In part one of a new ‘What Happens Next?’ series, Guy Kesteven has some dark warnings about what’s going to happen to a lot of bike brands in the next few years

Trek Marlin being ridden in a desert

The Taipei show is the biggest trade bike show in the world. You can go there as a punter but its primary purpose is for far eastern vendors to sell their stuff to the biggest bike brands . Unsurprisingly, given that anyone who is anyone is probably there, it’s also the biggest place for bike industry gossip. 

'Right sizing'

Right now, what everyone is talking about is Trek reporting that they’ll be reducing their bike range by 40 percent and the size of their overall business by 10 percent going forward. Yes, that Trek! The solid, dependable, privately owned Wisconsin-based brand has been rock solid since it started selling touring bikes in the 1970s. The Trek who most industry people were saying pulled a blinder by allegedly using their scale and cash reserves to guarantee the supply of parts when production and delivery choked during Covid. That meant Trek was the first to get big shipments of bikes after everyone had sold out and the sheer amount of Marlin hardtails they dropped into dealers has achieved mythical status.

Unfortunately, while they sold a huge amount of bikes to people wearing face masks, there are still a lot of Marlins in shops – and there are probably more in warehouses all over the world. So Trek is doing the smart thing and making fewer bikes going forward. Because otherwise that backlog of Marlins is never going to get sold and Trek will hemorrhage even more money storing them or selling them for less than a profit. And while their use of the phrase ‘Right sizing’ is definitely corporate ‘posi–speak’, the decision to downsize even based on pre-Covid levels is almost certainly correct.

The news that old dependable Trek is making big changes to stop future oversupply is a big deal, but they are far from being alone in this. From the sound of the rumor drums there are other very big companies, as well as many mid-sized and mini brands that are totally constipated with stock. And in many cases that’s not just because they ordered too much, but because they have a whole ton of very closely spaced products. Orange's multitude of visually near-identical, single pivot hand-made monocoque bikes made it hard for customers to pick an obvious winner and nearly put them out of business. I can’t help wondering if the reason Santa Cruz are running very big discounts on some bikes right now is because there are so many to choose from the confusion is enough to put people off. 

In contrast, Yeti has a pretty clear and clean product lineup and is still currently selling bikes full price. Other brands like Whyte and Norco have also massively reduced their product portfolio to help them leapfrog ahead of brands buried in out-of-date stock. In the case of Whyte, it has even sidelined projects they’ve been working on for years to put nearly all their eggs in the E-Lyte basket. After speaking to Jason Schiers and Clive Gosling from GT at Core bike show , it’s clear they’ve done the same. Canceling whole bike lines just before launch so they can concentrate on a few really strong new offerings.

Brands on the run

While figures like a 40 percent reduction in bike range sound dramatic, it doesn’t have to mean a loss of family favorites. Trek in particular produces a huge size range of bikes and generally makes each model in multiple colors. So it could be that every bike stays, but only in the best-selling color or with fewer options spanning the sizing spread. Not great if you're an odd size or like a choice of aesthetic, but not a disaster.

But for brands that have already slimmed downsizing and hacked the options back to a minimum, things will be a lot harder in the months and years ahead. There’s less room to maneuver too as geometry is now basically all the same and while internal storage is a nice feature, I’ve never heard anyone chopping in their perfectly good old bike just to get a snack hatch on the new one. Unless you’ve got a genuinely different suspension technology that people actually want (buyers are traditionally very averse to new tech until it’s multi-proven), then realistically how many almost identical 4-bar or twin-link carbon bikes with a 64 to 66-degree head tube do we need to choose from?

And while brand loyalty or re-polishing faded memories of past glory days will work with us old gits who’ve been hanging around the sport for decades, we aren’t the people brands need to attract to stay alive.

Power rangers

The people brands need to attract are the new mountain bikers, who may have dusted off an old bike during Covid or who just found MTB from fresh and are now encouraging their mates to join them. These riders are a very different breed with different brand and buying values. While old schoolers are used to glitches and bodges being part of biking and were prepared to put up with random customer service and extensive research to find the right next bike, the new breed isn’t. They don’t want a confusing sea, as far as they can tell, of identical bikes. They want stuff that works rather than needing to be nursed and they want it presented, sold and serviced professionally. And we might kid ourselves that this is the case in the bike industry, we all know that for every slick showroom and logo polo shirt, there’s a bargain bin in the corner and an ordering process that’s still based on paper stuck on spikes. But the whole chat about retail is for another time.  

The big thing that these new buyers mean is a total change in brand recognition and that’s also tied very heavily into the rise of the e-bike. 

E-bikes are not the miracle cure

What I mean is that while some of these new buyers might recognize the big brands like Specialized , Santa Cruz, Canyon , Shimano , or Trek, they’ll definitely spot Bosch as a brand name to go towards because their power tools, domestic appliances, auto parts, etc. are recognized as costing a bit more but return great reliability. Some outsiders might know Giant bikes, but the smartest move of the world’s largest bicycle manufacturer is to team up with Yamaha for their motors. With a lot of e-MTBers coming from an off-road motorbike background, brands like GasGas and Husqvarna are going to stand out a lot more than Haibike or Cube . Even if you get a better spec for a lower price by going for the latter. I can’t help feeling that brands like Bosch and Yamaha are going to get sick of having to deal with hundreds of relatively tiny bike company intermediaries to access the cycling market and will just make their own bikes.

There are other big players poised too. As soon as Porsche is confident that their investment in Fazua motors is a sound one, why wouldn’t they go direct through their existing dealers with all the upsell and aspirations they bring? Honda is already starting to show concept bikes again too and it’s clear that this personal mobility part of the market is becoming increasingly interesting to the auto industry. Hell, why wouldn’t Apple go for a quick positive spin on their entry to personal urban mobility by following up their failed ‘self-driving car’ project with an ‘Apple Bike’? They recently added a ton of cycling-friendly features to their Apple Watch and regardless of its actual performance, you can guarantee it would sync with all your other devices instantly and look brilliant. Not something you can say about every e-bike from current manufacturers. 

But then maybe that’s a good thing. Talking to managers at bike brands, they’re certainly beginning to realize that as the e-bike market matures, it’s not the fairy tale, fortune-creating cash cow it looked like at the start. Whatever the brand or design, e-bikes have a far higher return/warranty rate, up to 100 percent in some instances. Nobody ever had their house or warehousing destroyed and insurance companies get startled by a conventional bike catching fire either. 

They also require far more parts to order, stock, integrate, and wait for delivery on. That's after going through a whole extra level of explosive category shipping headaches and costs and being hamstrung if they don’t turn up. While it’s a pain if SRAM changes its transmission and makes your existing stock look dated overnight, if a motor brand makes your entire inventory electrically extinct that’s a huge issue. Because while the higher ticket price of an e-bike is a win at the till, when those units aren’t shifting then they’re sucking up a whole lot more cash. Which is of course the whole issue we started with in the first place.

Finally, what the pandemic and subsequent sh*t show have clearly demonstrated is that bike and component brands know as much about their customers, demand and sales trends as a triathlete knows about suspension setup. In fact, the spike, rebound and sag in sales we’ve seen recently is almost certainly worse than the back-end performance of a bike set up by someone in Speedos.

While the amount of talk around inclusivity, diversity and lowering entry barriers is definitely increasing and that’s a brilliant thing, I can’t help feeling it’s not really gaining traction yet either. That losing a hundred grams, changing head angle by a degree, or increasing tire space still gets more high fives in boardrooms and marketing agencies than something that will engage with hundreds of thousands of new riders, change their headspace, or genuinely open up cycling to whole new communities and demographics. 

And these topics of advocacy, retail, racing, riding and media are all things I’m going to dig deeper into in this series. So for now, go enjoy the fact that there are way more bikes and brands than we need, and often being sold at bargain prices. Because one thing I’m sure of is that the situation isn’t going to last forever and if you end up buying bikes from the same place as your washing machine, then don’t say I didn’t warn you.

The Definitive Guide to Sizing a Vintage Mountain Bike

  • 5 Min To Read
  • 03 Jul, 2023

An old piece of vintage mountain biking equipment is a great addition to your collection. Bike sizing has changed over the years, so the 1915s frame design is quite different than the 2000s.

Unfortunately, the current mountain bike sizing charts cannot be used to measure vintage bikes. This is especially true if you want to be exact. However, this is not the end. If your bike is vintage, you can still use the vintage measurement process and compare it with the current size chart.

Vintage Mountain Bike

Let’s begin with a brief overview of vintage bikes. Vintage bikes are a collection of old bikes that dates back to before and after 1915. Vintage mountain bikes are defined by their age in the mid-1980s.

The vintage bikes were not designed to be used on the mountain, but only for road riding.

Vintage Mountain Bike Sizing?

How can you comprehend the bike’s size, which is not consistent with the current mountain bike sizing standards.

Let’s take a look at the different sizing methods our counterparts have come to trust over the years.

Method 1: Using the Inseam Measurement

Although the inseam measurement can be used to date the mountain bike size, it is not the same as the vintage mountain bike size.

How can you ensure the correct inseam length? Stand with your legs apart at a maximum 8 inches.

Next, measure the length of the tape starting at your crotch. Make sure it is the topmost portion of your legs, not your pants. The tape measure should be lowered until it touches the ground.

If it is too difficult to measure yourself accurately, a partner can help.

If you are unsure about your crotch or are unsure about your pants, you could place a book between your legs and feel the top of your pants. Next, measure from the ground to where the book ends.

Your inseam measurement will determine the right size vintage bike. Instead of multiplying this by 0.66, as with current mountain bike sizes, subtract 14 from your results. Your answer should give you the correct size mountain bike that you should compare with vintage bikes.

Method 2: Stand Over Method

If you’re lucky enough to buy the bike in a store you can use the stand-over method. This is when you stand on the bike astride and get ready to go for a ride. However, your legs are on the ground.

Your crotch should be at least an inch from the top tube to achieve the perfect size bike. However, your mountain trails will determine the exact spacing.

For example, if there are more people riding in downhill conditions, spacing can be as high as 7 inches. For cross-country trips, you will need to space your riders four inches apart.

Why is the spacing important? If you’re standing or trying to adjust your seat, the spacing will protect your crotch. The more difficult the situation, the greater the space should be.

Method 3: The Seat Tube Sizing

This is the most common method of sizing bikes, including mountain bikes. To find the best fit, you will need to measure your height and inseam.

The seat tube measurement begins at the bottom of your seat post and continues down to the section where the pedals align.

This measurement will give the bike measurement. You can also use your height to determine your best bike.

These are the top three ways to get the right mountain bike size. These methods can all be used simultaneously to achieve the right mountain bike sizing.

Frequently Asked Questions (FAQs)

What size vintage frame do i need.

It would be helpful to have a vintage bike frame that is appropriate for your height and length. This will depend on what type of vintage bike that you are looking for. Is it a mountain bike or a road bike? You can use the above three methods to build mountain bikes.

You can use the same methods as above to purchase a roadbike. However, there may be slight variations. If you measure your inseam, you will notice a smaller spacing between the top tube (and the crotch)

Does it matter if my bike frame is too big?

Yes. You will have to strain to pedal if your bike frame is too large. You will not be able to pedal at the speed your large frame allows.

Should I get a medium or large mountain bike?

The size you need will depend on your height. Mountain bikes are more efficient in smaller frames than road bikes. Make sure to measure your frame first.

The large mountain bike is best for tall people. Medium-sized people prefer small mountain bikes. It all depends on your measurements and the bike.

What size mountain bike should I get for my height?

The smallest size is XXL if your height ranges between 4?10 ft and 5 ft. The size ranges can take up to three inches to reach the next size. The XXL mountain bikes are comfortable for riders between 6?4 and 6?6 feet.

Wrapping Up

Although owning a vintage bicycle can boost your self-esteem and accomplishments in the world of cycling, most people buy them for their fun. They are heavier than modern mountain bikes and therefore more difficult to pedal. A new bike will be more suitable for you if you are looking to race.

For a comfortable and fit bike, it is important to measure your vintage mountain bike. It should be your first consideration before you rush to buy the bike.

Ultimate Guide for Vintage Mountain Bike Sizing

For the adventurous mountain bikers, an old vintage piece adds an excellent antique to your collection. However, bike sizing has changed over time, and the 1915s frame builds quite different from the 2000s design. 

Vintage Mountain Bike Sizing

Unfortunately, you cannot use the current mountain bike sizing chart to measure the vintage bike size. That is especially more if you are looking for accuracy. Nevertheless, this is not the end of the game. If the bike is vintage, why not apply the vintage measuring process and probably make a comparison with the current bike size chart?

Vintage Mountain Bike

Let’s start with a summary of the vintage bikes. Essentially, vintage bikes are an old collection, dating before and just after 1915. However, the period that defines vintage mountain bikes goes to the mid-1980s. 

Unlike today’s mountain bikes that consider several features for a better mountain ride, the vintage bikes only considered off road riding success.

Vintage Mountain Bike Sizing?

How do you understand the size of these bikes, which do not conform to the current mountain bike sizing standards?

Let’s have a look at the various sizing methods that our counterparts have learned to trust over the years.

Method 1: Using the Inseam Measurement

Though the inseam measurement is used to date to determine the correct mountain bike sizing, this goes back to the vintage mountain bike sizing.

How do you ensure that you get the right inseam length? Simply stand with your legs slightly apart, at a maximum of 8 inches. 

Then, using a tape measure, take the length starting from your crotch, ensure that it is the topmost part of your legs and not the pants. Lower the tape measure until it touches the ground. 

Let a partner do it if accurate measurements of yourself become too difficult to get. 

If you are not sure about your crotch area and are confused about your pants, you can as well put a book in between your legs until you feel it from the top. Then, take the measurements from the ground to the topmost part of the book.

Finally, the results you get from your inseam will dictate your right vintage bike sizing . Rather than multiply this by 0.66 as with the current mountain bike sizing, subtract 14 from the results. Your answer should tell you the correct mountain bike size that you should consider with vintage bikes.

Method 2: Stand Over Method

If you are lucky to get the bike from a store, you can try the stand over method. This means that you hop on the bike the stand astride, as if ready for a ride, but with your legs on the floor. 

For a perfect bike size, your crotch should have some space from the top tube. Nevertheless, the exact spacing will depend on your mountain trails.

For instance, if you have more instances riding rough downhill conditions, the spacing can even go as far as 7 inches. On the other hand, if you are in for cross-country expeditions, four inches apart will do the task.

Why the spacing? The spacing will protect your crotch from harm in case you are standing and trying to adjust your seat. The rougher the situation, the bigger space should be.

Method 3: The Seat Tube Sizing

This is the most commonly used sizing method for bikes, including mountain bikes. You will use the measurement against your height and inseam to know your best match.

So, the seat tube measurement starts at the bottom of the seat post, running down the post to the section where the pedals align with the frame.

This measurement will give you the bike measurement, which you can use your height to gauge your best bike.

These three methods are the top guides to realizing the best mountain bike sizing for you. You can use them all simultaneously to get the correct mountain bike sizing for you. 

Frequently Asked Questions (FAQs)

What size vintage frame do i need.

It would help if you had a vintage bike frame that is suitable for your height and inseam. However, this will depend on the type of vintage bike you want to purchase. Is it a road bike or a mountain bike? For mountain bikes, you can use the three methods given above.

If you intend to purchase a road bike, you can use the methods above, with slight deviations. For instance, if you measure your inseam, the spacing between the top tube and the crotch is smaller.

Does it matter if my bike frame is too big?

Yes, it does. If your bike frame is too big, you will strain to pedal and probably hurt your legs. Besides, you will not pick up speed at the rate the large frame allows you to ride.

Should I get a medium or large mountain bike?

Get the right size based on your height. Mountain bikes tend to work in smaller frame sizes compared to road bikes, so get the measurements first.

If you are tall, the large mountain bike will do. However, medium-sized people look for small mountain bikes. It will all depend on your measurements versus the bike.

What size mountain bike should I get for my height?

If you range between 4’10ft and 5’2 ft, you should get the smallest size, which is XXL. the size ranges take up to three size inches to get to the next bike size. At 6’4 ft to 6’6 ft, you can comfortably ride on the XXL mountain bike size.

Wrapping Up

While owning a vintage bike adds to your ego and achievements in the world of biking, in most cases, you invest in one for fun. They are much heavier compared to the contemporary mountain bikes, hence more difficult to pedal. Thus, if you are up for a race, a new bike will serve you better.

However, if you are purchasing one, vintage mountain bike sizing is necessary for a comfortable and fitting bike. Actually, it should be your top consideration before rushing to get the bike.

You are here, cabda east attendees share opinions on trek's impending cuts.

By J.P. Partland

MEADOWLANDS, N.J. (BRAIN) — We asked retailers and suppliers at the CABDA East show this week about the “right-sizing” program that Trek has planned , and what it will mean to the rest of the industry. 

Larry Black, Mount Airy Bicycle, Mount Airy, Maryland (a current Trek dealer):

“I heard they're planning to cut 40% of their SKUs and I think that's a great idea. Most people should. They should make the catalog half the size if not smaller, and don't have models every $60. This has been a big obstacle since I started selling Trek in the late 70s. This has been a serious obstacle: too many models too many colors …

Larry Black

“As far as the 10% cut, whatever that means — workforce maybe, cutting jobs? Yeah, I think too many of these companies, based on my experience, are trying to grow artificially. They are trying to grow horizontally instead of vertically. I’d rather see vertical growth, which means more integrity, better service. Fewer but better. 

“Trek has been trying to do too many things. Now they are trying the Red Barn thing, which is used bikes. I know more about used bikes than they do because I’ve got 5,000 of them. But that’s just another complication and I think some of that might take advantage of consumers in the wrong way. The downside is some of the consumers who might think they need the variety don’t really need the variety. And I can tell you from experience: I think right sizing is one of the smartest things anybody can do, not just Trek.” 

Marc Cianfrone, Pop’s Bicycle Shop, Somerville, New Jersey (a Trek dealer):

Marc Cianfrone

Benita Warns, co-owner of Midway Bicycle Supply and Mr. Michael Recycles Bicycles, St. Paul, Minnesota:

Benita Warns

"For shops, obviously if there's a little less product around they won't have as many things to choose from, but on the other hand that could be a positive because then shops will get a little more freedom to be able to operate without having to having to buy everything from Trek and not be allowed to buy from anybody else. That's very, very restrictive, almost to the point of being protectionist — who owns the shop? The shop is supposed to be owned by the owner of the shop, not their supplier."

Amos Brumble, owner of Brumble Bikes in Westerly, Rhode Island: 

Amos Brumble

“I think it's probably the right move; it’s going to be painful for everybody and I hope it leads to a better business model in the future and gets them away from … trying to cover all the bases, which I think the bike market doesn't support. There's going to be some dealers that are going to depend on certain SKUs that are going to get cut and it’s going to affect them. They may have to fill that in with a different product line and that can be hard.”

Peter Henry, former owner and current board member of Landry’s Bicycles in Massachusetts (a Trek dealer. No photo available):

“Specifically on reducing the number of SKUs they are about 30 years overdue to make that move. They would make more money, and their retailers would make more money, if they streamlined their product offering and had less confusion and fewer SKUs and fewer inventory problems. So I think it's a really smart move on their part and I don't know why they're finally doing it now, probably for the wrong reason, but what whatever the reason, we will take it."

(For shops) "If the right sizing means that they're going to reduce service levels to retailers, that’s a problem. I mean, if their sales are not adequate to make their numbers, to support the payroll level that they have, obviously they need to deal with that. If they went out of business, it would be far worse for retailers. So you have to do what you have to do. But the reducing the number of SKUs for bikes is just plain positive and long overdue and I wish that some of the other suppliers would do the same."

Phil Cohen, Chain Reaction Bicycles, Evans, Georgia:

Phil Cohen

"Well in these times where everybody is struggling no one is immune to those sorts of factors. I just see it as a company trying to do what they think is best for their business.”

(Could it be a negative for retailers?) “If a company doesn't offer the support the dealers need, that could be a negative effect, but there's a lot of turmoil in our industry right now and I know it's probably gonna be a year or more before things settle out. It’s gonna be a rough ride until then and nobody’s immune.”

Shane Hall, Bicycles NYC:

Shane Hall

“I think the challenge for us is finding what is the new normal. This is something we’ve been talking about for a while now: We knew what the pre-pandemic normal was and we kind of settled into that. During the pandemic sales went through the roof and so now the question is where are we now? Where is the new normal of what do you buy, what do you forecast, how much product do you keep in stock? How much product do the vendors actually buy for the season? We have to figure that out now."

"I haven’t seen any cuts from other suppliers yet, I have seen bike sales prices dropping and looking at other industries you’ve seen cuts at large companies, so this isn’t surprising."

The bike industry is "in chaos" says boss: so what do Trek’s plans to ‘right size’ mean for the industry… and you?

The bike industry is "in chaos" says boss: so what do Trek’s plans to ‘right size’ mean for the industry… and you?

First Published Mar 12, 2024

In the latest development in the bike industry’s stormy commercial conditions, Trek Bicycle says that it plans to “right size” by cutting spending by 10% and reducing the number of individual products it offers by 40% over the next two years. This was originally reported by Bicycle Retailer and Industry News . 

For those not fluent in corporate jargon, rightsizing is “the process of restructuring a business to meet new objections and increase efficiencies”, according to Forbes . In other words, Trek is changing things up to save money, although it says its overall strategy remains unchanged.

Trek John Burke (1)

How do we know this? Although Trek has yet to announce anything officially, Bicycle Retailer and Industry News has got hold of an internal memo sent by company president John Burke to executives. Yeah, crafty. He said that these changes are a response to slow sales and high levels of inventory – the downturn in the bike industry’s fortunes, essentially.

John Burke said Trek would reduce overall spending by 10% with cuts to programmes and positions, with decisions on this made on or before last Friday (8th March). As mentioned, those decisions have yet to be made public.

Trek’s stock-keeping units (SKUs) in the 2026 model year will be 40% lower than in the 2024 model year. An SKU is a separate product that a company offers. If a particular product is available in several sizes and/or different colours, that all adds to the number of SKUs offered.

Does this mean Trek’s 2026 bike range will be 40% smaller in two years? Possibly, but bear in mind that Trek has a huuuuuuge range. As well as the road and mountain bikes you’re probably most familiar with, it also sells loads of city bikes, electric bikes, children’s bikes, cruisers, you name it. Trek sells a helluva lot besides bikes too – everything from stabilisers and kickstands to T-shirts and toe-covers – so let’s not get too alarmist. We’re unlikely to see the demise of the Madone, Emonda or Domane anytime soon.

John Burke is quoted as saying, “These are turbulent times in our business”, and he went on to say that the global bike market is “in chaos” with high stock levels at wholesale and retail levels, leading to “significant and continued” discounting.

Judging by pretty much everything that we’ve been hearing since the end of the Covid-induced bike boom, that’s a fair comment. You only have to take a look online and you’ll see huge discounts right, left, and centre as companies try to shift stock that’s cluttering up warehouses and shops to make way for the new stuff that’s on order.

In the UK, the apparent impending demise of Wiggle Chain Reaction Cycles – at least in its current form – is only exacerbating the situation. How does anyone compete with a massive powerhouse that’s having a final clearance sale and selling off bikes at 30-50% off?

> It's our Bike of the Year but should you buy the Vitus Venon EVO-RS Force AXS All-Road bike at 30% discount?

John Burke said that retail sales were below the levels forecast by Trek and that the company had not hit its monthly sales goals for the past 15 months. Rather than simply hoping for better days ahead or continuing to make cuts around the edges, he said Trek had to “right-size our business to the realities of the marketplace”.

> “You have to dig in for the next three to five years”: What lies ahead for a struggling bike industry in 2024? 

In Trek’s case, reducing the number of products it’ll be offering also chimes with the company’s drive towards sustainability. Trek outlined its intention to launch a trade-in and refurbishment scheme last year, initially confined to the United States of America, to cut down on waste and extend the lifespan of its bicycles, even if that means making and selling less. That said, whether Trek’s plans to rightsize result in producing less overall or simply offering fewer options remains to be seen.

2024 Trek Domane SL 6 - 1 (1)

What are the implications of Trek’s decisions? We’ve spoken to several industry insiders who, off the record, say that we could be about to see many other major companies rationalise their activities to increase efficiency.

During the pandemic, we saw a huge shortage of bikes and equipment. It’s only three years since we ran a story on road.cc: Britain’s bike shortage, part 1: what’s going on, when will supplies return, and how can you improve your chances of bagging the bike you want?

Wow! Back then, bike brands could sell pretty much whatever they could produce, and they were falling over themselves to add new production lines and even build entirely new factories. How times change.

Are we likely to see similar moves from other big companies? Yes, even though most will probably manage to enact their right-sizing strategies more privately, without leaks to the media.

Bicycle Retailer and Industry News quotes Steve Fenton, owner of Pro-Lite Manufacturing , as saying, “I might be going totally against the grain with what I'm going to tell you, but I think it's the right thing to do, and actually if I was in charge, I'd be doing it on a much bigger scale. My opinion is that all (the big brands) have to do it.”

Is right-sizing likely to affect some areas of the bike market more than others? It’s possible, yes. Most mountain bikes tend to be more complex than most road bikes due to their suspension systems; there are more parts involved. The same goes for electric bikes. Our industry contacts say that these sectors are likely to be hit by rightsizing more than road bikes where the options on offer can be potentially reduced far less. That’s a bit of a simplification, though. Different companies are likely to be affected in different ways depending on their own particular exposure to overstocks in certain areas.

2024 Trek Domane SL 6 - 3

Naturally, we have contacted Trek for comment, but got a big “no comment” from those guys. Maybe they’ll release a full statement at some stage. We did, though take the opportunity to ask Ian Whittingham, Co-Founder/ Director of Sigma Sports, for his take on the situation.

“I think a lot of this makes sense,” he said. “I think it’s a good time to reset and have a look at what you're offering, to consider whether you really need that many colour options or model options within each range. It’s probably quite a sensible move by Trek for their size business. It’s certainly something we've done in the last couple of years post-COVID. “We’ve been trying to curate our ranges a bit better than we might have done before to make sure we were in stock with the right stuff rather than big, broad ranges of products.”

Funily enough it will be all about making bigger profits.  If they were serious about sustainability they would manfacture as close as possible to local markets.  They won't and people will defend them for it.

I'm not sure that works. Multiple framebuilding and assembly factories on each continent, parts shipped to each one then distributed 'locally' in a radial or similar fashion is not cheaper or as efficient otherwise many brands would have done that already. It's similar to why local bakeries, skilled trades and craftspeople have been put out of work - it's cheaper to buy shitty Chorleywood 'bread' and thousands of other items (including many non-food products) from a supermarket instead of a local shop.

Centralising manufacture and assembly to one centre of excellence (in this case mainly Taiwan, which isn't too far from where many components are manufactured) and sent around the world in containers seems more sensible to me.

And it's not necessarily about bigger profits but remaining profitable in a shrinking market instead of carrying on as before then going into administration, as has happened to any number of brands, distributors and retailers.

Trek is an equivalent of a slow, wobbly oil tanker with too much weigth on the very top, too many captains on the bridge, too far from the rest of the crew. 

I believe it is high time for big companies to try cheaper components. There are groupset companies that are practically unknown yet they are way cheaper and with better reviews. Make your base model as cheap yet good as possible but also open to upgrades (hate to see 7 speed base models from big brands) and money will follow.

Ah, but what price do the big companies actually pay? I'll bet it's not the full rrp that even single clients don't cough up, but much, much less.

Sure the OEM prices they pay are much cheaper, but given that a bike cost now as a groupset, every cost saving is welcome especially at lower spec bikes. At higher end models, I am sure that there are people happy to pay crazy prices for bikes.

So Trek is finally having to address their haphazard way of doing business where they added way too many products and options in search of increasing top line revenue, while jacking up prices on everything (as most of the bike industry has been doing) in order to increase profits despite the poor planning and execution.  Corporate greed is a constant, it's just a matter of which was the executives are currently attempting to implement it.

Now they'll cut product options and staff to ensure they can continue to reap the same rewards from the lower revenues since the Covid bike boom is long over and a lot of cyclists aren't willing to deal with bikes, even with some of the current steep discounts still being more expensive (even inflation adjusted) than their equivalent 10 years ago. The eye watering price of middle to top tier bikes that aren't much different than those bikes, except some aero improvements that have a negligible impact to 99% of the buyers since we don't ride at pro level speeds needing those questionable 10 seconds over 40k at 45kph....

Trek has gone way overboard with how many different models they sell, they have at least 60 different bikes, and that doesn't include children's bikes.

Heck, personally I think all they really need is 5 within each category, they have 4 categories and 1 child category, which would leave about 25 bike models.

Chop at least half of those would save Trek a lot of money, and prevent as much confusion among buyers as to what to get.   

Like a lot of companies, they've got far too many performance models; are they really all needed? Similarly, I had a look at their alloy MTB Hardtails; Marlin, Roscoe, X-Caliber, Procaliber......Are all those really needed?

You've listed entry and performance models for both trail and XC race hard tails. I doubt there is much market for a cheap line of dedicated race bikes, when that product space is covered by the lower spec options of the Procaliber. The proliferation of SKUs in the MTB sector have also been compounded by the COVID boom coinciding with the rise in popularity for 29" FS bikes, which has blurred the lines further between use case product categories. Where there used to be XC, trail/AM, Enduro and DH, XC still sits in the 100-120mm travel range, but now there's also Down-country, Enduro has grown and split into short travel enduro and super-enduro. Who even knows what to class a 140mm travel bike as now?

If they're serious about cutting SKUs and sustainability then they should move away from the annual refresh cycle, it's madness. Shimano don't release a new group each year. We don't need 8 new versions of the Giant Defy when they're still busy selling '22 inventory. Only replace a model when there's a fundamental shift (e.g new geo to accommodate wider tubeless tyres)

This! Component brands don't do it, car brands don't do it, motorcycle brands don't do it, and bicycle brands shouldn't do it either. Nobody should care if a bike is 'last year's model' as long as its tech (or look) is not too outdated.

But it's generally only the paint scheme that changes from year to year. The frame stays unchanged for maybe 4-5 years. The automotive industry does similar, with cosmetic changes (light clusters, bumpers and grill) changing while the metal underneath stays the same.

So, get your aero 650b gravel commuting bike now, before ultra-niche product catagories are rationalised out of existance.

It's more likely that they will cut the number of options for each bike - groupset/spec level, colours, maybe even sizes. And as the article states, a lot of the SKUs will be for parts and accessories.

Trek GB's website shows 12 road helmets (with up to 5 colour options for each); 12 MTB helmets (ditto, 42 options); 29 commute/fitness helmets and 7 kids' helmets. Almost all of them will be available in multiple sizes. SKUs a-plenty!

When you consider that the helmet market has many established brands then does it really make sense for Trek to stock and promote up to 200 helmet models of their own?

The Equipment category encompasses everything from handlebars, pumps and panniers to phone & tablet accessories. There are 17 models in Shoes. The £150 Circuit road shoe is available in 13 sizes and 5 colours, that's potentially 65 options for a single model. That category also lists overshoes, 3 footbeds/insoles in 5 sizes and parts including Bontrager branded SPD and 3-bolt Look-compatible cleats. They sell 8 models of bottle cage, one of which has 12 colour options.

The handlebar category lists 95 items, quite a few of which are Speed Concept aerobars & very specific parts. This is a shrinking market, even triathlon is seeing a significant drop in participation and there are very few people interested in the blinged-up, barely used TT/tri bikes I see advertised online.

I don't consider this to be either wise or sustainable. It would be too simplistic to say "Trek should just focus on selling bikes" but there are surely good (and it seems now pressing) reasons to reduce inventory and the overheads associated with the 'everything with our name on it' path they have gone down.
