Trek Marlin Buyer's Guide

Trek Marlin Overview

Who is a Trek Marlin for?

The Trek Marlin is durable, easy to outfit with gear and accessories, and at home on many types of terrain.  This makes it an ideal mountain bike for beginner cyclists looking for versatility at a good price point.  

Commuters will appreciate the frame mounts for a rear rack, 29" or 27.5" wheels for smooth and efficient pedaling, and 4" of front suspension to take the edge off the ride. 

The Marlin is capable on the mountain too.  It'll gobble up less technical XC trails like the Bonneville Shoreline Trail on the east bench in Ogden.

Why you might love a Trek Marlin

VALUE!  The Marlin is not only a high-quality and versatile mountain bike, it's also super affordable!  It's built with the best component spec per price point that ensures you won't outpace the bike as your cycling skills advance and your adventures get more technical.

The Marlin comes in seven frame sizes (XXS to XXL) to comfortably fit riders of practically  any height! For the smallest sizes, they've included unique fit features like a curved top tube for easier dismounting.

Race-Inspired Geometry

Trek engineered the Marlin to have the look of an XC-racing bike while prioritizing comfort for beginner riders.

Internal Cable Routing

Looks awesome!  No unsightly cables to be seen. Internal cable routing on the Marlin means you don't have to fret about dirt, grime, and inclement weather contaminating your cables.  

Marlin Gen 3 vs Marlin Gen 2

• Trail focused geometry: Gen 3 Marlins have a more trail focused geometry that includes a slacker head tube angle, a steeper seat tube angle, and a longer reach than the Gen 2 models.  
• Chain stay guard: All Gen 3 Marlins come with a full length chain stay guard to protectthe frame and keep things quiet on the trail.

Trek Marlin 7 Quick Overview

Trek marlin 7 main features, does trek marlin 7 fit your needs, verdict: good value or not, trek marlin 7.

Get From Trek

Trek has obviously put a lot of effort into making Marlin 7 Gen 2 a gateway model to some of their higher-priced and higher-specked lineups such as Roscoe or Supercaliber.

Marlin 7 has features from both the entry-level and the mid-range world. It has excellent competition-worthy suspension , brakes, and frame, coupled with a low-level Shimano groupset and a heavier-than-ideal wheelset.

With a few smart upgrades, it can certainly become a bike that can lead you to a cross-country race podium!

Light and Efficient 1×10 Drivetrain

One of the high points of the Trek Malin 7 bike is its light and efficient 1×10 drivetrain. It’s built with an 11-46T cassette.

This means that it has an excellent range of gears .

High-Performing 100mm RockShox Fork

The RockShox Judy fork on Marlin 7 is a big improvement compared to the SR Suntour forks found on other lower-priced Marlin models.

It puts 100mm of travel under your hands but also equips you with a preload function and a Turnkey lockout. Therefore, you can lock it with the flip of a switch even when you’re riding.

The coil spring might make the fork feel a bit inefficient if you are very short and light, but if you have an average weight, you’ll be happy with it.

This fork is ready for fast descents , rocky terrain, and more technical trails.

Budget-Friendly Components

Shimano Deore components are an upgrade from the previous combination of Shimano Altus and Shimano Acera.

Deore is part of the Shimano lineup, the groupset is the cheapest group marketed towards real mountain bikers.

Deore is well-built and reliable, it even shares some features with more expensive groupsets.

Race-Ready Frame Geometry

By far the most important part of any bike is its frame. Trek Marlin 7 can be proud of its Alpha Silver Aluminum frame as its light, compliant, and nimble on the trails.

The race-inspired geometry makes this bike good both at tight and demanding singletracks, as well as at straight downhills attacked at high speeds.

Its 69.3-69.5-degree head tube angle combined with a 73.5-71.9-degree seat tube angle puts you in a good position to have maximum control.

Reliable Hydraulic Disc Brakes

The Shimano MT200 hydraulic brakes are a phenomenal mid-range choice. They are capable of providing you will all the braking power you need when attacking high-speed descents.

Combined with the aluminum Bontrager Connection double-wall wheels and knobby Bontrager XR2 Comp tires, you’ll get  maximum confidence in bends and in wet conditions.

These wheels are not tubeless-ready . Still, they can be easily converted to a tubeless setup which would give Marlin 7 even better trail properties.

To figure out whether or not Marlin 7 is the right bike for you, you first need to define your needs. If trail riding is your hobby or you believe that it might become that, then you should definitely buy Marlin 7. This is a race-ready bike that you can enter amateur competitions with or just have fun with your friends.

But, Marlin 7 is still not too trail-specific that it cannot accomplish other tasks as well. If you can only afford one bike and you want to be able to commute on it as well, this bike can do that.

A few miles on paved roads to get to work will feel like second nature. Best of all, on the way back home, you can hit some trails and end your day the right way.

hi jeff im planning to buy marlin7 1,030 dollar DO I NEED TO CHANGE THE PEDAL IM GOING TO PERU INKAS TRAILS DO YOU THINK IS GOOD BUY TO TRAVEL THERE AND MAKE SOME HILLS IN MACCHU PICCHU TRAIL MOU

Hey Miguel, in my opinion, the stock pedals are perfectly fine. The only reason why you might want to change them is if you want to switch to clipless shoes and pedals. Otherwise, stick with the stock ones and enjoy your trip!

The Trek Marlin 7 Has The Heart Of A Race Bike

This cheap mountain bike is the perfect gateway drug to your next (trail riding) addiction.

The Takeaway: The Marlin 7 combines race-inspired geometry with budget-friendly components for a versatile bike that’s ideal for aspiring racers and commuters alike.

• Aluminum frame with race-ready geometry
• 2 x 9-speed drivetrain
• Available in seven sizes from XS up to XXL

Price: $799 Weight: 31.4 lb.

It strays from the single chainring trend that’s common in off-road bikes at the moment, but two chainrings is a very good compromise for the smaller number of rear cogs in a nine-speed drivetrain–you typically don’t see 1x drivetrains until you step up to a 10-speed. The 22 x 36 smallest gear on the Marlin 7 is an easier gear than the 32 x 50 smallest combo often found on bikes equipped with SRAM’s much more expensive Eagle 12-speed drivetrain . The 36 x 11 combo, the largest gear on the Marlin 7, also outpaces the the 32 x 10 available with a more expensive 12–speed drivetrain, so you get more go-fast gearing as well. An added bonus with a 2x drivetrain is smaller jumps between gears, making this an excellent choice for an entry-level mountain bike.

Rack Mounts

Rear mounts make this a good choice for touring and commuting.

Fork Lockout

This switch is easy to reach while riding and handy when you’re rolling on pavement and don’t need the front suspension.

2 x 9 Drivetrain

The 36/22 chainrings give you all the go-fast and get-up-the-hill gearing you’ll need.

Gear Indicator

The display on the rear shifter serves as a nice reminder of which gear you’re using.

Internal Routing

Hidden cables add to the sleek and fast aesthetic of this bike.

As racers we like to say “look fast, feel fast, go fast” –meaning you can’t go fast if you don’t look good. And the Marlin’s sharp lines and aggressive styling are sure to make you feel speedy as soon as you swing your leg over the top tube.

Trek Marlin 7 Details

Style: XC Material : Aluminum Wheel Size: 27.5 for XS and S, 29 for M through XXL Fork: 100mm RockShox XC30 Shifters: Shimano Altus 2 x 9-speed Front Derailleur: Shimano Altus Rear Derailleur: Shimano Acera Cranks: Shimano MT101 Chainrings: 36/22 Cassette: 11-36 9-speed Brakes: Shimano MT200 Hydraulic Disc Wheels: Aluminum Bontrager Connection Tires: 2.2-inch Bontrager XR2 Comp Saddle: Bontrager Arvada Seatpost: Aluminum Bontrager Handlebar: Aluminum Bontrager Stem: Aluminum Bontrager, Blendr compatible

Marlin Family

If you like the idea of the Marlin but some aspects of the 7 don't appeal to you, be it price, components, or some combination of those, there are a handful of lower-cost options available. Those models keep the same frame, but trim costs by downgrading the components and suspension fork.

The Marlin family also boasts two women-specific models that feature a lower stand-over height as well as shorter cranks, narrower handlebars, short-reach brake levers, and women’s saddles. Both the Marlin 5 ($550) and Marlin 6 ($650) are offered in men’s and women’s versions. The cheapest option however, the $480 Marlin 4, is only available in a unisex model.

Race-Inspired Design

While we joke that you have to look good in order to go fast, good looks can only carry you so far if the bones aren't good. In this case, when you look at the geometry you can see that this bike is extremely race–capable. The first standout is the 73 degree effective seat tube angle. Paired with a 69.5 degree head angle and 1159mm wheelbase (for our size XL test bike) you get a bike that'll be aggressive and nimble in tight singletrack, yet stable when barreling straight downhill at high speed. These are design elements you're just as likely to see on much pricier bikes made for high level competition. But don't let that scare you away from using this bike for purely recreational pursuits. It's perfect for that as well. In fact, the real gold in this bike is the fact that it's equally good as a casual weekend cruiser as it is an entry level racing bike.

Shimano 2 x 9–Speed Drivetrain

The 2 x 9-speed drivetrain blends Shimano Altus shifters and a front derailleur with the nicer Shimano Acera rear derailleur. The rear derailleur handles the bulk of the shifting load , so using a better rear derailleur with cheaper shifters is a good way to maintain drivetrain performance while still keeping overall price as low as possible.

Trek Marlin 7

Shimano MT200 hydraulic disc brakes are more than capable of providing the level of control necessary for pushing your limits on high-speed descents. The bike rolls on aluminum Bontrager Connection hoops wrapped in Bontrager XR2 Comp tires and laced to aluminum quick-release hubs. These wheels aren’t, however, tubeless ready. That shouldn’t be a deal-breaker given it helps keep the final price as low as possible, and any wheelset can be easily converted to tubeless . That said, you don’t need to upgrade to tubeless to ride trails, but it does make for a better experience by allowing you to run lower tire pressure without fear of pinch flats. Lower pressure also softens the bumps and gives you better traction. If you want to make the leap to tubeless, any local bike shop should be able to guide you toward a cost-effective way to make the switch.

Ready to Throw Down

The Marlin 7 may be a cheap mountain bike , but it has the heart of a race steed. Unlike some bikes on the cheap end of the spectrum that cater to the recreational user, this one is aimed firmly at entry-level riders who want a bike that’s affordable yet capable of riding and racing hard. That was readily apparent from the first few pedal strokes. With the aggressive styling of the dramatically sloping top tube and the aggressive fit , this bike can grow with you as your addiction, ambition, and skill set grow. You can easily upgrade the components over time, and since the frame is aluminum, it’ll be able to handle multiple seasons of use.

Out in the woods, this bike does exactly what you’d want when riding hard. Agile steering and impressive shock absorption from the coil-spring RockShox XC30 fork make the Marlin 7 surprisingly adept at traversing extremely rocky and technical trails. It tracks nicely on fast sweeping turns, although on rough terrain it was more difficult to hold the line due to running high tire pressure–I tested this bike as-is without making the tubeless conversion. At just over 31 pounds, it’s not the lightest XC bike but still light and lively enough to clear knee-high logs. If this is making it sound like I loved this bike, that’s because I did. For new NICA racers and dirt-curious riders of all ages, the Marlin 7 is a worthy option.

Trek Marlin 4 Gen 2 Review: A Capable Budget-Friendly XC MTB

Trek Marlin 4 is the second cheapest model in Trek’s mountain bike range, at just $630. 

This stylish, modern-looking hardtail is a solid introductory bike for day-to-day riding, commuting, and leisurely weekend spins on gravel and dirt trails. 

Although it looks the part, the Marlin 4 can’t handle actual mountain trails, as the low-performance fork won’t take much abuse. 

This Trek Marlin 4 review will provide a detailed look at the bike, its strengths and weaknesses, and the type of rider who should buy it. 

What Is the Weight Limit on a Trek Marlin 4?

The weight limit on a Marlin 4 MTB is 300 lbs, which includes the bicycle, rider, and cargo. The bike weighs just under 32 lbs, leaving around 268 lbs for the rider and cargo. 

• Sleek design with internal cable routing
• Shimano drivetrain
• Cheap 
• Heavy, low-performance fork

Trek Marlin 4 2023 Full Specs

Trek marlin 4 gen 2 full review.

The Trek Marlin 4 2022 is the same as the 2023 model. It has a basic 3×7-speed Shimano Altus/Tourney groupset and Tektro mechanical disc brakes, a typical pairing for the price range. The SR Suntour XCE 28 isn’t worth much on mountain trails but takes the sting out of bumpy gravel trails and roads. 

This section will cover the features and components that make the bike stand out in its price category. 

Is the Trek Marlin 4 a Trail Bike?

The Trek Marlin 4 is not a trail bike. Trail mountain bikes typically have above 120mm of travel, and the majority of models are full-suspension. Instead, the Marlin 4 is a light-duty off-roader better suited to urban riding and gravel trails.

If you want a proper trial bike, check our list of the best full-suspension mountain bikes out there.

Stylish Alpha Silver Aluminum Frame

The whole Trek Marlin series uses the same Alpha Silver aluminum frame. However, at less than half the price of the premium model, this frame is a notable strength of the Marlin 4. 

Marlin 4 has full internal cable routing, which is a popular feature that not all mountain bikes in this price range offer.

Trek’s Alpha Silver frame comes from years of materials innovations and design expertise, resulting in a balanced ride quality that balances stiffness and compliance compared to the overly stiff aluminum frames typical of this price range. 

This frame also has sleek internal cable routing that gives the bike a higher-priced finish and mounts for a rack and kickstand for commuting or even light bikepacking. 

What Is the Difference Between Trek Marlin 4 and 5?

There isn’t a big difference between the performance of the Trek Marlin 4 vs. 5. The Marlin 5 has a slightly more robust fork, improved 2×8-speed gearing and hydraulic disc brakes, and a slightly lower weight. However, the Trek Marlin 4’s price is $110 lower than the Marlin 5 . 

Progressive Sizing

The Trek Marlin 4 2023 comes in seven different sizes, with almost two feet in between the shortest and tallest recommended heights. The company uses progressively sized wheels and components and a modified top tube for the smaller bikes to deliver the same performance for each rider . 

The XS and Small sizes both have a curved top tube which lowers the standover height, which shorter riders have issues with, and ‘Smart Wheel Sizes’ means the smaller sizes get 27.5″ wheels instead of 29ers. In addition, the brake levers, handlebars, stems, and cranks all change throughout the size range. 

Reliable Bontrager Componentry 

Trek Bikes’ in-house brand Bontrager provides the whole build kit aside from the groupset and fork. These are well-made components that will stand the test of time. In addition, they are easy to replace by visiting the Trek online store. 

Premium all-black finish and quality Bontrager parts help Trek Marlin 4 look good and provide better value for the money.

It’s worth noting that the saddle, handlebars, seatpost, and stem are the same across the five Marlin bikes, which benefits the Marlin 4 and increases its value as it is the cheapest. 

Trek Marlin 4 Gen 2 Sizing Chart

• XS — 4’9″-5’1″ / 145-155cm
• S —  5’1″-5’5″ / 155-165cm
• M —  5’5″-5’8″ / 165-173cm
• M/L — 5’8″-5’11” / 173-180cm
• L —  5’11”-6’2″ / 180-188cm
• XL —  6’2″-6’5″ / 188-195cm
• 2XL — 6’5″-6’8″ / 195-203cm

Who Is Trek Marlin 4 Gen 2 Best Suited For?

The Trek Marlin 4 mountain bike is suitable for urban riders, commuters, and anyone who enjoys riding on light off-road paths, fire roads, and gravel trails. 

By equipping Trek Marlin 4 with a rear rack and kickstand, you can use it for commuting, running errands, or even bikepacking.

The level of components is typical for this price point, and they perform as expected. However, there are clear limitations to this bike’s capabilities off-road. So if you’re looking for a capable XC mountain bike, this isn’t it. 

Anyone looking for a cheap, reliable run around that doesn’t sacrifice style will appreciate the Trek’s Marlin 4.

Is Marlin 4 Gen 2 a Good Buy?

We believe the Trek Marlin 4 Gen 2 is an excellent buy in the ~$600 price range, easily competing with similarly-priced hardtails like the Cannondale Trail 8 or Co-op Cycles DRT 1.0. 

Trek bikes are renowned for their reliability, and with the Marlin 4, you’re getting this reliability at an unbeatable price. And if that wasn’t enough, it’s got a sleek modern design that makes it look more expensive than it is. 

Consider the Marlin 4 if you want a Trek mountain bike that doesn’t break the bank and will get you from A to B in comfort and style.

I purchased the Trek Marlin 7 during the pandemic to get out and ride again, and often. Well, it worked. Over the next couple years, stamina, ability

The frame is mid weight with flexibility to control through jumps, landing and control. The "package" that Trek puts out really is nice and sleek. I look at many other frames, some still boxy and dated. The Trek series pairs size, components and aesthetics well. The color choices look engaging.

If you are looking at this Mountain Bike as truly, "entry," I'd leave it alone. To look at your future with the Trek Marlin 7, you will need to account for future upgrades. Even though the weight is satisfactory, more advanced riders may want to slim down.... I was able to improve by adding more nimble components, upgrading with carbon fiber were I could. I plan to keep this bike for a long time and will continue to change things to progress the ride.
