The New Trek Émonda Is Faster Than Ever

Already one of the fiercest climbing bikes available, the new Émonda is even faster thanks to a dose of aero.

The Takeaway: The Émonda SLR is a benchmark pro race bike—and it’s surprisingly rider friendly.

• It has 183 grams less drag than the previous generation, but the frame is only 33 grams heavier
• There are 10 models starting at $2,699
• SL models ($2,699 to $5,999) have the aerodynamic shaping and features but in a frame that’s about 400 grams heavier than the SLR
• SLR models ($6,699 and up) use a new carbon fiber composite that’s 30 percent stronger than Trek’s previous top-of-the-line carbon.

For Émonda SLR bicycles, Trek will provide an individual handlebar and stem until an updated handlebar/stem combo is available.

Additionally, all customers who bring in their handlebars for replacement will also receive a $100 in-store credit that can be used toward any Trek or Bontrager merchandise through December 31, 2022.

Remember professional road racing ? It’s that thing where super skinny people go unbelievably fast up and down hills and fly over flat roads for hours at a time. It’s been a while since the pros have beat up on each other for our entertainment, but there might, hopefully, be some races on the horizon. When the races do resume, Trek’s pro riders will be aboard its new third-generation Émonda climbing bike. The new Émonda isn’t lighter, but it is faster thanks to a dose of aerodynamic tuning.

Now With Aero

The new Émonda gets a major drag reduction with a tiny weight gain.

Simple Seat Mast

The seat mast has lots of adjustment range, and an easy-to-use saddle clamp.

Light and Slippery

The new Bontrager Aeolus RSL 37 wheels are light, sleek, and stable.

Wide and Threaded

The T47 bottom bracket has a wide stance, and user-friendly threads.

A built-in chain watcher prevents unwanted derailments.

Making the new Émonda frame more aerodynamic wasn’t exactly a tough hurdle as the previous Émonda had virtually zero aerodynamic optimization. But adding meaningful aerodynamic benefit while achieving the frame stiffness expected of a pro-caliber race bike, maintaining the well-regarded handling properties of the previous Émonda, and adding rider-friendly features like a threaded bottom bracket—all with adding only 33 grams (SLR frame, claimed)—is quite a feat.

Below you’ll find my review of the Émonda SLR—I’ve been on it since early March—followed by a dive into the technology and features of the new bike, and a brief model breakdown.

Ride Impressions: Émonda SLR 9 eTap

The Émonda SLR is a tool made to fulfill the needs of some of the world’s best road racers. This bike will never be as comfortable or versatile as a gravel bike. Going fast on pavement and climbing performance are its only goals. These are obvious facts, but that’s the lens through which it must be viewed. And through this lens, it is one of the very best.

The new Émonda was born out of a request from Trek’s pro racers and pitched as the company’s “fastest climbing bike ever.” So little surprise they set me up with the lightest model (the SLR 9 with SRAM Red eTap ), which also has a build kit almost identical to the team’s bikes. It’s also, excepting customized Project One builds, the most expensive model at a buck under 12 grand.

That massive pile of clams gets you an aerodynamic frame with disc brakes, power meter, and wireless electronic shifting that weighs less than 15 pounds (54cm). And that’s with a hefty T47 threaded bottom bracket unit, lustrous paint , clincher wheelset, a chain-watcher, standard butyl tubes, 37mm deep rims, 160mm disc rotors front and rear, and SRAM’s largest Red cassette (10-33). That’s “Holy shit!” impressive.

By cutting drag a ton without adding much weight, it’s hard to argue with Trek’s claim that the new Émonda is faster than the outgoing generation. But if you have any doubts, they’ll be erased when you ride it. This is an explosive bike: it feels as light as a feather and as solid as a steel girder at the same time.

Trek’s Émonda has always been a raw and rowdy bike that feels a little wild and a bit dangerous in precisely the ways you want a race bike to feel: That’s not lost with the added aerodynamics. If anything, the new Émonda is even crisper and punchier than before, which is saying something.

A small downside to all this fury is the Émonda’s smoothness. Light and stiff race bikes aren’t a smooth-riding lot to begin with, but even measured against a stiffer riding genre, the new Émonda is on the firmer end of the scale. Still, it escapes harsh or punishing labels—I did a six-hour ride on the Émonda on the stock 25 tires and didn’t feel worn down by its ride. Swapping to 28s helped a lot (no surprise) and were on the Émonda for the bulk of my testing. I’d suggest reserving the lighter and more aerodynamic stock 25s for racing or PR attempts—assuming good roads—and use 28s as daily drivers.

The Émonda’s handling is excellent. Well, let me caveat that: Road racing geometry is pretty uniform, so whether I’m on a current race bike from Trek, Specialized, Cannondale, Cervélo, Canyon, Colnago, Wilier, Pinarello, BMC, Giant (etc., etc.), I find the broad strokes of their handling feel and performance quite similar. There wasn’t anything about the Émonda’s handling or cornering performance that set any new benchmarks for me, but there wasn’t anything to dislike either.

It was quick and accurate, diving into corners with a light touch. It offered great feedback, so I always knew where I was relative to its and my limits, and I could count on it to be consistent and predictable. It was maybe a touch less settled in bumpy corners than the Specialized Tarmac, but the Émonda never broke traction or skipped. Overall, for such a light bike, the Émonda is remarkably solid and drama free. I’d have no qualms barreling down a technical alpine descent on the Émonda.

I received this test bike in early March, giving me plenty of time to ride it back to back with its primary competition—a Specialized S-Works Tarmac , what I consider the benchmark for aero-ized lightweight bikes. The Tarmac is smoother over the bumps and has a silkier feel overall, but the new Émonda feels more efficient, like it can go faster more easily.

I’ve also ridden a good slice of the Émonda’s competition, including the Canyon Ultimate CF SLX , Colnago V3Rs, Cannondale SuperSix Evo , Cervélo R5, Wilier Zero SLR , Pinarello Dogma F12 . These are all superb bikes, but I feel the Émonda is the class leader. It feels sharper and more explosive than all of them. It feels faster, and that’s what matters most in a race bike. But I also like that the Émonda is pretty straightforward and rider-friendly.

For example, I swapped the stock one-piece bar/stem for a standard stem and round bar. One, I could run a standard bar and stem on this bike, which you can’t say about every modern race bike. And two, I didn’t have to pull any cables, wires, or hoses to make the swap: Again, something you can’t say about all race bikes. For the record, the shape of the one-piece Aeolus bar/stem is great, and the tops are the most comfortable to grab of all the aero-topped bars I've used. The only reason I swapped is my preferred length and width combination (110x40) wasn't available yet.

The BB is threaded, which makes it easier to service and replace than a press-fit (however, I was getting some noise out of the BB area, which I never resolved). The wheels employ standard offset, and it uses regular thru-axles. It’s compatible with pod-style power meters and mechanical shifting. Its signature seat mast is pretty much the only non-standard thing about this frame, and even then, it’s pretty user-friendly. There’s no cutting necessary, height adjustment is ample, the saddle clamp is easy to use, and it’s travel-case friendly.

I expect so much from a modern high-end pro-level road racing bike that it’s hard to exceed those expectations. It’s rare when a bike does: The Émonda SLR is one of those rare bikes.

Team Request

The new Émonda is partially a result of a request from the Trek-Segafredo race team. “They are one of our primary customers,” said Jordan Roessingh, Trek’s director of road product. “And they started to realize that it’s not just weight, it’s not just stiffness and responsiveness, there’s this other thing—aerodynamics and speed—that’s also really important to be competitive and be faster on the bike. They had been one of the loudest voices saying, ‘We need the lightest-weight, stiffest bike possible.’ And now they started coming back saying ‘We need those things, but we also need the bike to be faster in order for us to be really competitive.’ ”

It is (comparatively) easy to make a light frame, it is easy to make a stiff frame, it is easy to make an aerodynamic frame. Making a frame that’s two of those three things is more challenging: Making a bike more aerodynamic usually makes it heavier, making a bike lighter typically makes it less stiff, etc. Making a frame that is light AND stiff AND aerodynamic enough to satisfy the demands of a top-level professional race team is extremely difficult.

But not impossible. Many brands already make a light, stiff, and aero bike. The Specialized Tarmac is one, as are the Canyon Ultimate, the Cannondale SuperSix Evo, the Cervélo R5, the Wilier Zero SLR, the Pinarello F12, the Scott Addict, and the new Giant TCR . All of them seek to balance the three qualities—light, stiff, and aero—in the pursuit of the ideal race bike, and they all manage the balance differently. The common thread between these bikes: They’re all used by teams that compete against Trek-Segafredo.

Still Light, Now With Aero

The previous generation Émonda SLR Disc , launched in 2017, was an extremely light frame at 665 grams (claimed). But when a frame is already that light, it is much harder to make it even lighter. At least lighter enough to make a meaningful difference.

So, Trek took a different approach to making its climbing bike faster—instead of lighter, it made it more aerodynamic. The new Émonda frame is a touch heavier—yet still extremely light at 698 grams—but the bike has 183 grams less drag than the previous generation.

The important thing to note here is that, though the frame is more aerodynamic, the 183 gram drag reduction is not from the frame only. New wheels and a new aero bar (more info on both below) play a role. The specific setups Trek used to get that 183 gram number are: 2018 Émonda with 28mm-deep Bontrager XXX 2 wheels, and Bontrager XXX Bar/Stem Combo compared to the 2021 Émonda with 37mm deep Bontrager Aeolus RSL 37 Wheels and Bontrager Aeolus RSL Bar/Stem Combo.

Another drag saving upgrade: the housing, hoses and wires for the controls are almost fully inside the frame. They dive into the frame at the head tube passing through the upper headset bearing. The front brake hose runs into the fork steerer and down the left leg before popping out just above the brake caliper. The fork steerer’s flattened sides provide room for the rear brake hose and derailleur control lines to travel down and into the frame. Though it has flattened sides, the fork steerer is still compatible with standard 1 1/8” stems.

The overall drag reduction results in a bike that is 18 seconds per hour faster when climbing an 8.1 percent grade (the average grade of Alpe d’Huez ), and 60 seconds per hour faster on flat roads than the previous Émonda. Trek also claims the new Émonda is 13 seconds per hour faster than a Specialized Tarmac when climbing an 8.1 percent grade (all assuming the rider maintains a constant 350 watts).

Eight Point One Percent

With three qualities—aero, stiffness, weight—that work in opposition to each other, how do you decide how much to optimize one quality when you know it will negatively affect the other two? How aero is aero enough? At what point is improved aerodynamics offset by the weight added to get there?

The team behind the Émonda used a legendary climb to help them decide: Alpe d’Huez. “It represents an extreme example of what most people see on a regular basis when they’re doing a big climbing ride,” said Roessingh, “It’s around an 8 percent grade, and it’s about an hour-long climb for the pros—amateurs might go a little slower. It gives us a good understanding of what the benefit of a drag savings is relative to a weight savings.”

By optimizing the weight and aerodynamic balance around this climb, Roessingh claims the Émonda is faster on Alpe d’Huez and also faster on everything shallower than the famous climb, “which is the vast majority of the environments that most riders are going to ride in, including the team,” said Roessingh. “So if we can say it’s faster up Alpe d’Huez, it’s going to be significantly faster everywhere because the flatter it is, the more aerodynamics benefit you.”

Computer-Aided Optimization

Achieving the weight to the aerodynamic balance of the new Émonda required careful design of each tube shape. Aiding the Émonda’s team was supercomputing horsepower. The abridged and simplified version of the process goes like this: into the computer was fed a rough draft of the shape based on Trek’s aerodynamic experience and other information like UCI regulations. The program then varies the tube’s parameters within a predefined range and spit back several iterations of the shape, each with a different weight to aerodynamic balance. The Émonda’s team evaluated the alternatives and picked the one most suited to its location in the frame and best able to help the frame achieve its overarching goal.

Roessingh says that Trek cannot afford to buy the computing hardware necessary to run the CFD and FEA optimizations (in a timely manner) that helped shape the new Émonda’s tubes. The processing happens in the cloud where Trek rents time on Google, Microsoft, or Amazon’s supercomputers. It’s more affordable than buying a supercomputer. Even so, it is not cheap, “Cloud computing is becoming a relatively significant budget line item for us because we’re doing so many of these optimizations in CFD and FEA and all that processing happens in the cloud.”

The new Émonda’s fork legs, head tube, down tube, seat tube, and seat stays all use a variation of a truncated airfoil. The top tube and chainstays, which have virtually no effect on drag, are optimized almost entirely for stiffness to weight.

In Trek’s line, the new Émonda’s aerodynamic performance is equal to the third generation Domane ; the Madone is still significantly more aero. But while the more aerodynamic Madone is faster in flatter terrain, once the climb hits about 5.5 percent, the lighter Émonda becomes the faster bike. And for many of the Trek-Segafredo team riders—and many amateurs—that means the Émonda is fastest when it matters most: the hardest part of a race or ride, which is almost always on a steep climb.

OCLV 800 Carbon

Getting the new Émonda SLR to be as light as it is while adding aerodynamic shaping would not be possible without employing a new carbon-fiber composite, said Roessingh. The new OCLV 800 composite is 30 percent stronger than Trek’s previous top-of-the-line composite (OCLV 700). Because it is stronger, they can use less: By using OCLV 800, Trek’s team was able to make the Émonda SLR frame 60 grams lighter than if they used OCLV 700.

The Émonda SLR is very cool, but it’s also very expensive (bike prices start at $6,699). For the 99 percenters, there’s the Émonda SL (models start at $2,699).

The SL uses OCLV 500 composite, and the frame is quite a bit heavier than the SLR’s. The SL’s frame comes in at 1,142 grams, with a 380-gram fork (SLR fork weight: 365 grams).

But material (and weight) are the only difference between the SL and SLR.

Aeolus Bar Stem

While a ton of work made the Émonda’s frame tubes faster, a big chunk of the new bike’s drag savings comes from the one-piece Aeolus bar stem. It alone is responsible for 70 grams of the Émonda’s 183-gram drag reduction. This means that if a traditional stem and round bar are installed on the new Émonda, its drag advantage over the previous-generation bike drops to 113 grams. And it means that you can make any bike with a round bar and traditional stem significantly more aerodynamic by merely installing the Aeolus. Retail price is $650.

The integrated Aeolus is made of carbon-fiber composite, of course, with a claimed weight of 297 grams (42x120). It’s offered in 14 length and width combinations, from 44x120 to 38x80. Hoses, housing, and wires run externally for easier service and repairs, but in a groove that keeps them out of the wind. A bolt-on plate keeps the control lines tucked and organized where they turn off the bar tops to run in line with the stem.

The Aeolus employs a mount that works with Bontrager’s line of Blendr accessories for mounting computers and lights.

Aeolus 37 Wheels

Another new Bontrager product rolling out with the Émonda is the Aeolus 37 wheelset. It comes in two models: the Aeolus RSL 37 (1,325 grams/pair, $2,400) and the Aeolus Pro 37 (1,505 grams/pair, $1,300).

The RSL 37 is claimed to be lighter than Zipp’s 32mm-deep 202, yet more aerodynamic and more stable than Zipp’s 45mm-deep 303. Both wheels are disc brake only (only Center Lock interface), tubeless compatible, use DT-Swiss internals, have no rider weight limit, and come with a lifetime warranty.

Surprisingly Rider Friendly

Though the new Émonda is clean and integrated looking and uses high-performance standards, it is also remarkably rider-friendly. Cables, hoses, and housing run externally on the one-piece Aeolus bar/stem for easier repair and service (with one exception: wiring for a Shimano Di2 or Campagnolo EPS bar-end junction box runs partially inside the bar). If you prefer a more traditional cockpit, it can be run with a standard bar and stem with 1⅛-inch steerer clamp.

The bottom bracket uses the threaded T47 standard , which is compatible with almost all common crank-axle standards.

Front and rear thru-axles are standard 12x100 and 12x142mm, and the wheels employ a standard dish. The standard flat mounts for the brake calipers are compatible with 140, 160, or 180mm rotors.

Tire clearance is officially 28mm, but that’s with a ton of extra space. I fit 32mm tires in the Émonda with ease.

And though all models do use a seat mast, it’s a no-cut variety with lots of adjustment range.

H1.5 Geometry

Trek did offer its top-of-the-line race bikes in the aggressive H1 geometry for riders seeking an ultra-long and low geometry, or H2 which was an endurance fit. The new Émonda is offered only in H1.5, which splits the difference between H1 and H2. The result is pretty typical dimensions for a modern race bike—a 54cm Émonda H1’s geometry is remarkably similar to a 54cm Specialized Tarmac.

There are eight sizes starting at 47cm and topping out at 62cm.

There are 10 models of the new Émonda. SL models start at $2,699 and are priced up to $5,999. SLR models start at $6,699 and go up to $11,999.

Only SLR models come with the Aeolus integrated bar/stem stock; and only the Émonda SL 7 ($5,499) and up come with the Aeolus 37 wheelset.

The new Émonda is a disc brake-only platform.

Project One

The new Émonda is in Trek’s Project One paint and parts personalization program. If that’s not luxe enough for you, Trek’s Project One Ultimate program allows you to work with a designer to come up with a one-of-a-kind finish, and Trek will source any parts you want for your new bike.

Trek Emonda SL6 Pro review

Trek's latest GC/climbing bike has undergone an aero transformation, but has it helped?

• Sign up to our newsletter Newsletter

The radical changes brought about in this new Emonda frame are somewhat hampered within the SL range owing to the heavier nature of the frame and subsequent ride quality of the 500 Series OCLV carbon. It is a solid all-round performer and there's no getting away from the fact the ride quality provides a good balance of efficiency and ride comfort. It's just if you were looking for an improvement on the ride of the previous model you'll need to hold off and get one of the higher level SLR models to truly see improvements.

Efficient power transfer

Excellent handling prowess

Compliant ride

New SL frame has lost some of the excitement of the existing Émonda

Heavy for a 'climbing' bike

You can trust Cycling Weekly. Our team of experts put in hard miles testing cycling tech and will always share honest, unbiased advice to help you choose. Find out more about how we test.

Trek recently released a brand new re-imagining of the Emonda, the brand's lightweight climbing/GC model platform, featuring a drastically aero-ised chasis. The model family is split into a higher tier SLR and the lower SL range that this SL6 Pro sits in, the critical difference is in the carbon layup and the enhanced integration sported by the SLR range.

The frame on the Emonda SL6 Pro is constructed of Trek's own 500 Series OCLV carbon fibre. This carbon layup might be heavier than the newly showcased ultra light 800 Series OCLV of the top level SLR Émonda's but is considerably more economical to produce, helping keep the SL range prices in a much more affordable tier.

>>> The Trek Madone gets an update, but you won't spot it

The new Emonda features a completely new set of tube shapes, most of which have gone down the aero route. But Trek is at pains to keep the comparisons to the Madone aero race bike to a minimum; this isn’t simple a ‘Madone Lite’. Rather than being the same elongated shapes as found on a proper aero race bike, the aero shaping of the Emonda’s tubes is much more subtle and is based around the principle of unsteady aerodynamics.

>>> Best road bikes reviewed

In this case it’s more about how drag is affected through wind gusts and other factors at slower speeds than the usual 45km/h, after all, not even pros climb at these speeds. There are still the characteristic truncated airfoil shapes that we associate with aero frames but the effect is far less dramatic and produces a frame that still has a traditional look.

Trek Madone SLR9 Disc review

Trek hasn’t jumped on the dropped seatstay bandwagon with the new frame either, preferring to stick to a set of widely spaced yet aero shaped, thin seat stays.

The new frame also enjoys a little more integration, bringing it more in-line with the Madone. All models now see the cable routing brought neatly into the frame at the front of the headtube keeping the front end profile as slippery as possible.

The other notable feature of the new frame is a wholesale move to the T47 bottom bracket standard . This style marries the reliability of a threaded shell with the capability of running larger diameter internal bearings and enables Trek to maintain its characteristic wide and efficient bottom bracket stance.

The new Emonda range has also been designed with Trek’s middle-ground H1.5 geometry ensuring a set of numbers that sits it half way between the ultra-aggressive pro H1 and its laid back and relaxed, endurance specific H2 geometry. A tall stack of split spacers under the stem provides plenty of height adjustment for a wide range of rider requirements.

And finally, keeping the Emonda in a pretty rigid user set Trek has bucked another trend and limited tyre clearance to just 28c putting the focus of the bike purely on road going high performance.

The SL6 Pro sits near the top of the SL range and as such has a a pretty decent spec sheet. A mechanical Shimano Ultegra is the least we would expect at the +£3,000 price point and we don't need to point out how reliable and consistent it is in providing smooth shifting and braking.

As with the entire Emonda range the SL6 Pro runs on Bontrager wheels; Aeolus Elite 35 to be precise. These feature a carbon 35mm depth and complement the new 'aero' frame without compromising too much on weight and climbing ability. They feel stiff under power and spin up to speed relatively quickly. There are lighter and faster wheels that would suit the new frame but at this price point the Aeolus Elite is spot on. The tyres are Bontrager as well, in this instance 25mm R2 Hardcase Lite tyres. These are not Bontrager's fastest tyres, more classed as an everyday tyre with plenty of puncture protection.

In a complete whitewash the entirety of the finishing kit is also provided by Bontrager. Unlike the integrated carbon bar/stem of the higher end SLR models, the SL6 Pro is fitted with a standard aluminium handlebar and separate stem, allowing for much simpler cockpit customisation. Despite the more ordinary setup the cable routing is still really neat underneath the stem without needing any additional housing.

The Émonda maintains the 'reversed' seat post, with a larger diameter seatpost mast fitted over the seat tube. This allows for plenty of adjustment plus further lengths are available if needed. The Bontrager Aeolus saddle also stands out for being incredibly comfortable even when sat right on the nose.

I was curious to see if the new Emonda was able to improve on the ride quality of the highly rated existing version and the short answer is yes, well kind of....

The first thing to note is that in this new guise, the lower SL version I have on test feels a little chunky at over 8 kilograms - not something you expect when the bike's raison d'etre is all about low weight and climbing. However a total mass doesn't always equate to an anchor of a ride experience and this is true of the Émonda.

Trek has managed to provide a level of stiffness around the bottom bracket that enables the Émonda to deliver in its promise of rewarding effort. Granted it takes less effort to maintain speeds on flat and rolling terrain, much like the Madone aero bike, and I'm certain it is a 'faster' bike than the last version. But I can't help but feel that this new design has stifled some of the existing model's lively and exciting ride nature - it feels like using adjectives such as solid and dependable is more appropriate, almost like the Domane endurance bike.

Trek's relaxing of the geometry on the Emonda has increased its ability to keep you comfortable and riding hard on a long ride and I had no issue taking on some challenging and long routes around Dorset and South Wales. The tall stack of shaped and split spacers sit the cockpit a little too high for my personal preference but luckily I was able to drop the stem height by using some standard spacers on top of the stem, without needing to cut the steerer. This put a little more weight on the front wheel which enabled me to descend the Émonda with aplomb and happily stuff it into downhill corners at high speed without any of the vague feeling that can come with a front end that is a touch too high.

Climbing is where the Emonda should thrive and it certainly is no slouch on your typical British climb, however it doesn't set the tarmac alight and the near eight kilo weight does neuter the Émonda's ability to counter attack when your riding mates try to accelerate away from you on a climb.

It feels like I'm being a little harsh and critical of the Emonda SL6 Pro, after all in most respects it is a solid all-rounder and I have enjoyed my time riding the bike over the last few months. It's a great looking bike and I expect most riders will be satisfied with the performance, it's just I feel it has a lost a little of the magic the old version had. If you are looking for the sort of engaging ride the Emonda is known for I suspect you would need to save your pennies and opt for one of the lighter SLR options and certainly if it was my money that would be what I would need to do.

tire clearance w/Emonda SL6 (Ultegra brakes)

I've read a bunch of stuff on tire clearance on Emonda and sounds like it's pretty tight for 25mm. Seems to work with DA brakes but not with Red. I'm wondering about Ultegra? Anyone have experience with 25mm with Ultegra? I'd be looking at SL6 for example. Thanks!  

I just replaced the stock 23mm bontrager tires on my SL6 (64cm frame, ultegra 6800) with a pair of 25mm Continental Grand Prix 4000 SII's and they seem to fit fine. Inflated, the tires rub the brake pads as you slip the wheels back on, but they will slide past. It seemed like taking them back off while inflated wouldn't work as easily so I let the air out to do that.  

I have 25mm Continental Grand Prix 4000 SII's on my SL6 Emonda as well. No clearance issues at all so far (1,300 miles). As DonBjr mentioned they do rub the brake pads when putting the wheels on & off the bike, but i don't have to deflate mine. Thats probably a minor brake adjustment though.

First up, the comfort.

I picked up on the fact that the SL6 Pro has quite a firm ride – a little bit old school, dare I say. By that I mean that a lot of carbon fibre frames have become much more comfortable over the years as designers and manufacturers have learnt about carbon fibre grades, tube profiles and, more importantly, the layup of the composite material.

The Cube Attain GTC SL I tested recently highlighted this in the way that it really managed to reduce road buzz while retaining plenty of feedback through the frame and fork.

This isn't a criticism of the Trek at all, it just wasn't quite what I was expecting. I like it; I'm a big believer in ultimate performance over comfort when it comes to race bikes, and that is exactly what the Émonda delivers.

Stiffness throughout the fork and the lower half of the frame is very impressive, and means the Trek is responsive to your inputs. The wide bottom bracket shell allows for a large down tube and chunky chainstays to reduce flex when you are really nailing it, while the front end backs this up via the tapered head tube and firm fork legs. Sprinting and climbing are all taken in the Émonda's stride.

As you'd expect from a race bike, the riding position can be set up to be pretty aggressive – with a relatively short 151mm head tube length on this 56cm model I could achieve a low handlebar-to-saddle drop to aid the aerodynamics, especially when in the drops.

The rest of the geometry follows the same theme with a 73.5-degree head angle and a relatively short wheelbase for a disc-equipped frame (the chainstays are often a fair bit longer than those on rim-braked frames because of the extra axle width at the rear dropouts) at just 983mm.

Trek has achieved a good balance here with the Émonda I reckon.

The shorter wheelbase makes it nippy, which allows for snappy direction changes at high speed, yet it's managed to tame the handling just enough that the Émonda never becomes a handful unless you do something really stupid.

In my First Ride piece I mentioned that I hadn't managed to point the Trek at my favourite test hill, one that is fast and twisty with off-camber bends and chicanes. It really tests every part of a bike's handling in a blur.

Well, I have now, about five or six times, and the Émonda really impressed. It has the quickness in the steering and the overall agility to be pushed very hard into the corners.

After a night of heavy rain, gravel had been washed out into the lane slightly out of sight as I went into a fast left-hander at about 45mph; I dabbed the brakes a little, but seeing the grit and stones spanning the entire road there was no real way out of it. Letting the bike hit the gravel and predicting where the slide was probably going to end was the only option, and it was a sketchy couple of seconds.

As the front tyre regained grip on the asphalt there was a second where the still-sliding rear wanted to get in front, but the Trek's well-balanced handling allowed me to quickly regain control and blast to the bottom of the hill.

In less extreme circumstances the Émonda is an absolute hoot to ride downhill, with just slight adjustments to body position and the handlebar allowing you to flow from corner to corner.

On longer rides the Trek is just as well mannered; it is a very easy bike to ride quickly even when fatigue can kick in or when you are on unfamiliar roads.

The stiffness I mentioned earlier doesn't come through as a negative on higher mileage jaunts, especially if you get on with the saddle and have a decent pair of shorts on. The three- to four-hour rides I used the Trek on were a lot of fun. Unleash the power for the fun bits and then when you are on the flat, straight slogs you can just hunker down and keep the pedals turning over.

The only thing I needed to do was to shift the saddle 5mm closer to the bar than I would normally have it, because of the width of the top tube as it flows into the seatstays either side of the seat tube. I have quite large thighs and I could feel them rubbing on the frame every pedal revolution when I first started riding the Trek.

Frame and fork

The Émonda has always been the lightweight bike of Trek's road range, leaving outright speed to the Madone, but for this latest model Trek has incorporated more aerodynamic profiles in the Émonda's design.

Unlike most aero bikes, though, the Émonda's frame doesn't focus on being fast in a straight line or at high speed, it is a climbing bike after all. Instead the engineers have focused on 'unsteady aerodynamics', which fit in with the much lower speeds found when ascending.

Most of the attention has been placed on the front end, including the head tube and down tube. The top-end SLR models use the Bontrager XXX aero handlebar/stem combo which further increases the benefits, but that isn't available on the SL options.

The SLR models also use a new OCLV 800 grade carbon fibre while the SLs use the 500 series, which increases the weight a bit, although a claimed frame weight of 1,142g and 380g for the fork is far from shabby.

If wind cheating is your main goal then it's worth noting that the Émonda is optimised for 25mm tyres, as that is the most common size used for racing, but if you want something a bit wider 28mm will fit while still allowing 6mm of space around the tyre.

As you'd expect on an aero-based bike, the Émonda has full internal cable routing but this is taken to an extra level compared with most frames, with the cables and hoses leaving the handlebar and entering the frame through the spacers rather than the head tube or down tube. This gives much cleaner lines at the front.

You won't find a standard seatpost either. The Émonda's seat tube continues up past the top tube by a fair old way and then an external seat mast is placed over the top; you tighten the hex bolt to clamp it into place at the right saddle height.

The Émonda range is now completely disc brake-equipped which to my mind is a bit of a shame as I am a big fan of rim brakes, and it would certainly bring the weight down for a bike aimed at climbing.

Many manufacturers are seeing sales of disc models outstripping rim options by a large margin, though, so it is kind of inevitable. There is also the cost – the Émonda is available in seven sizes so that'd be 14 different moulds required if Trek offered both brake options.

The Émonda comes with flat mounts, as you'd expect, and 12mm thru-axles front and rear.

I mentioned the wide bottom bracket shell earlier and this is normally only achievable by using a press-fit BB, where the bearing cups are pressed into the frame. If tolerances aren't adhered to, creaking can occur, especially after water or grit gets between the mating faces, which is why we've seen many brands return to external threaded options.

Trek has gone for what is possibly the best of both worlds with the T47 system. First introduced by Chris King and Oregon's Argonaut Cycles , they thread into the bottom bracket shell which allows it to be wider, increasing stiffness without affecting the width between the pedals (Q-factor).

If you want a more in-depth look at what changes and design tweaks were made to achieve this new Émonda frameset then it'd be worth checking out Mat's full breakdown here .

Wheels and tyres

Trek says that the SL 6 Pro comes with all the lightweight components you need as standard, so there is no need to upgrade. You could save a few grams here and there, but overall it is a pretty complete package.

This model is the first carbon bike in the line-up that comes with a set of carbon fibre wheels. The 35mm Bontrager Aeolus Elite 35s are 35mm deep and are tubeless ready.

It's a good set of wheels for a whole range of riding styles: shallow enough to work on the climbs and just about deep enough to give you a small aerodynamic gain without being affected by crosswinds. Comparing the price of the near-identical SL 6 suggests you are getting them for just £450 too.

Reliability isn't an issue as they took on everything that was put in their way over the test period, and should anything happen and they get damaged Trek will replace or repair them for free in the first two years of ownership.

Wrapped around the wheels are a pair of Bontrager R2 Hard-Case Lite tyres. They are all right in terms of rolling resistance, grip and durability, but their 60tpi casing does give them a bit of a 'wooden' feel. You aren't getting a whole lot of suppleness which would really benefit the frameset, so I'd definitely upgrade when they wear out.

I've been using the R3 Hard Case Lites recently and they are a much better tyre, so something like that would be a good upgrade if you want to keep the Bonty/Trek theme going.

Drivetrain and brakes

On the SL 6 Pro, Trek is giving you a full Shimano Ultegra hydraulic/mechanical groupset and it suits the bike very well. You are getting near-Dura-Ace performance but at a much reduced price.

Trek has specced a 52/36-tooth semi-compact chainset and an 11-30 cassette, which is a great choice of gear ratios for a bike of this style. There are plenty of top end gears for speed work while the 30-tooth sprocket will give you an extra bailout gear over the more usual 28T found on the majority of race bikes.

The gear shifts from Ultegra are top notch. You get quite a light feel at the levers, but one that also gives a very nicely defined click so you can be sure that the shift has taken place.

When it comes to the braking, Trek has chosen to fit 160mm rotors front and back, which give more than enough power for a bike of this type.

Shimano's hydraulic systems are very powerful but also easily modulated thanks to loads of feel through the levers, allowing you to stop quickly without the fear of locking up the front tyre, even in the wet.

Finishing kit

All of the finishing kit is supplied by Bontrager, Trek's in-house parts department, and it's all decent quality stuff.

The handlebar is the Bontrager Elite VR-C which is an aluminium alloy model with a short reach and a shallow drop, making it ideal for a whole host of different riders' proportions. Helping that is the fact that different size frames get a different width bar, ranging from 38cm up to 44cm.

It's the same for the Bontrager Pro stem: the smallest 47cm bike gets a 70mm unit, with the 62cm extending that out to 110mm. The stem on each frame size seems to come up a bit shorter than most bikes of this type, but it seems to work.

I got on fine with the Aeolus Comp saddle. Its shape is well suited to riding hard and fast, and I like the firm padding which gives you a good platform to push against when you are really hammering it. (There's a separate review of it here .) 

This SL 6 Pro model has an rrp of £3,350, which isn't a bad deal for what you are getting here with the aero carbon frame, fork and deep-section wheels.

The similarly themed Scott Addict RC 30 is £3,199 and also come comes with an Ultegra groupset, but it is begging for an upgrade to the wheelset. It is light, though, at just 7.88kg.

If it's aero that you want then there is the Orro Venturi . The closest model in price is £3,299.99; you only get alloy wheels, but you are getting Ultegra Di2 for the gear shifting.

Overall, the Émonda is a very good bike. The aero tweaks have turned it into a very fast and efficient bike that still manages to deliver on the weight front and this SL 6 Pro model is so well specced there's no need to update anything when it comes to the components, just the tyres when they wear out.

A quality frameset that works both on the flat and the climbs, and well specced for the money

Tell us what the bike is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about the bike?

Trek says, "Émonda SL 6 Disc Pro is the first carbon road bike in the line-up that gives you lightweight carbon wheels to match your lightweight frame. Aero tube shaping, disc brakes and a high-performance drive train make it a great option for roadies who value great handling and lots of speed."

Where does this model sit in the range? Tell us briefly about the cheaper options and the more expensive options

There are five models in the range starting with the SL 5 which comes with a Shimano 105 groupset for £2,725, finishing off with the SL 7 with SRAM eTap at £5,250.

A frameset is also available for £2,200.

Tell us about the build quality and finish of the frame and fork?

A well made and finished frame and fork.

Tell us about the materials used in the frame and fork?

Frame – Ultralight 500 Series OCLV Carbon, Ride Tuned performance tube optimisation, tapered head tube, internal routing, DuoTrap S-compatible, flat-mount disc, 142x12 mm thru axle

Fork – Emonda SL full carbon, tapered carbon steerer, internal brake routing, flat-mount disc, 12x100 mm thru axle

Tell us about the geometry of the frame and fork?

The geometry is race orientated with a steepish head angle and a short head tube length.

How was the bike in terms of height and reach? How did it compare to other bikes of the same stated size?

The stack and reach figures are pretty typical for this size and kind of bike. This 56cm comes with a stack of 563mm and a reach of 391mm.

Riding the bike

Was the bike comfortable to ride? Tell us how you felt about the ride quality.

Overall it's fine, although it does have a firmer ride than a lot of new carbon fibre frames.

Did the bike feel stiff in the right places? Did any part of the bike feel too stiff or too flexible?

Stiffness is very impressive, especially around the bottom bracket area.

How did the bike transfer power? Did it feel efficient?

Efficiency is very impressive, it is a proper point and shoot bike.

Was there any toe-clip overlap with the front wheel? If so was it a problem?

How would you describe the steering? Was it lively neutral or unresponsive? Responsive.

Tell us some more about the handling. How did the bike feel overall? Did it do particular things well or badly?

The handling is very well balanced, making the Trek easy to ride whether you are just cruising along or pushing it hard through the bends.

Which components had the most effect (good or bad) on the bike's comfort? would you recommend any changes?

I liked the saddle, it was firm yet comfortable for all sorts of rides.

Which components had the most effect (good or bad) on the bike's stiffness? would you recommend any changes?

The Bontrager wheels offer loads of stiffness even when riding hard, out of the saddle.

Which components had the most effect (good or bad) on the bike's efficiency? would you recommend any changes?

I'd change the tyres for something a little more supple which would help you achieve higher speeds in the bends.

The drivetrain

Tell us some more about the drivetrain. Anything you particularly did or didn't like? Any components which didn't work well together?

The Shimano Ultegra groupset can't really be faulted. Gears and brakes offer great performance and reliability.

Tell us some more about the wheels.Did they work well in the conditions you encountered? Would you change the wheels? If so what for?

It's good to see a quality set of carbon wheels on a bike as standard at this price. They performed well in all sorts of conditions and seem to be durable.

Tell us some more about the tyres. Did they work well in the conditions you encountered? Would you change the tyres? If so what for?

The Bontrager R2s aren't bad, but the SL 6 Pro deserves something faster and grippier.

Tell us some more about the controls. Any particularly good or bad components? How would the controls work for larger or smaller riders?

Decent quality in-house kit that suits the bike well.

Your summary

Did you enjoy riding the bike? Yes

Would you consider buying the bike? Yes

Would you recommend the bike to a friend? Yes

How does the price compare to that of similar bikes in the market, including ones recently tested on road.cc?

For a semi-aero bike the Émonda is pretty well priced, like against the Scott and Orro mentioned in the review.

Use this box to explain your overall score

The Émonda's new aero frameset means that not only is it a good climber, it also works well on the flat sections too. The overall quality is very good and you are getting a well chosen spec. The firm ride might not be ideal for those who focus more on comfort, though.

Overall rating: 8 /10

8.23kg isn't 'lightweight'... that's porky. 1.4kg over the UCI minimum!

Not a big fan of the way the cables and hoses run at the front of the bar in order to fit under the stem like that, I'm surprised they haven't gone for a system where they run intrnally then under a stem cover etc

Quite a lot of money for an 8.2 kilo bike. 

"Comparing the price of the near-identical SL 6 suggests you are getting them for just £450 too."

The side by side comparison of the SL6 and the pro makes them identical bar the wheels. Which listed on the trek website retail at a price difference of £250, not £450. So either the stock wheels on the SL6 are over priced on their own (then maybe the bike is too) or the only reason to buy the pro is if the Aeolus are the wheel upgrade you want over everything else on the market.

I'm still more inclined to the RC30.

All-new Trek Emonda ALR takes lightweight frame tech to alloy models

• Click to share on Facebook (Opens in new window)
• Click to email a link to a friend (Opens in new window)

When Trek announced their Emonda carbon road bike line , they backed up their “world’s lightest” claims with an impressive frame and fork and an even more impressive 10.25lb (4.6kg) complete bike. Now, they’re adding an alloy Emonda ALR option that’s also lightweight yet far more affordable.

To earn the Emonda badge, the frame uses their top-level 300-series Alpha Aluminum that’s been hydroformed into size specific tubes, then welded together using a no-see technique that produces smooth joints that use less material to save weight.

The process is called Invisible Weld Technology, which they say produces stronger, stiffer welds despite using less material. Video, pics and more details below…

Trek told us the unpainted frame is 1050g (56), and a painted fork is 358g w/240mm steerer.

Like the ultralight Emonda carbon models, the ALR uses their H2 race geometry, E2 tapered headtube (standard 1-1/8″ to 1-1/2″) and wide Pressfit BB 86.5, meaning this bike is made to go fast. Other frame details include a braze-on front derailleur mount (no need to add a clamp if you’re getting the frameset) and external cable routing.

We’ve requested a more technical description of the welding process (update as we get it), but the frame is only part of the story. The complete bikes come equipped with built-in extras like the a Blendr stem with integrated light/computer mount, and it has Duotrap S compatibility (their ANT+/Bluetooth 4.0 speed/cadence sensor, sold separately for about $60).

You also get a complete group, so the Emonda ALR 6 with Ultregra gets a full Ultegra group from chain to brakes to cassette and everything else. There are no mis-matched parts or down spec’d bits to cut costs. A full carbon fiber tapered fork completes the package.

The Emonda ALR will initially come in two builds, the “6” with full Ultegra, Bontrager Race tubeless ready wheels with R2 tires, and a Bontrager cockpit with alloy short reach/drop bar and carbon seatpost for $2,249.99. Our local Trek Bike Store says complete bike weight is claimed at 17.25lb (7.82kg).

The Emonda ALR 5 drops down to a full Shimano 105 group with non-series Bontrager tubeless ready alloy wheels, R1 tires and a full alloy Bontrager cockpit for $1,759.99. Claimed weight is 18.77lb (8.51kg), colors will be the gloss black/hi-viz yellow and blue shown here, plus a racing red coming soon.

The frameset shares the same paint scheme as the “6” and comes with an FSA sealed cartridge bearing headset for $989.99. The frames have a lifetime warranty carrying a 275lb rider weight limit.

Just for fun, here’s the companion lifestyle video.

All three models shown here are available now and should hit stores soon. Our sources tell us there’ll also be an Emonda ALR 5 with Tiagra, an ALR 8 with Dura-Ace mechanical and ALR 9 with Dura-Ace Di2 coming soon. That last model suggests they’ll have an electronic-only frame, too, since these first models only have external cable routing. At the very top, in terms of light weight anyway, will be the ALR 10 with a full SRAM Red group.

looks like a rebadged Allez

The invisible welding looks a lot like what pretty much every other company calls smooth welding. And has been using for years. You weld the tube normally then go back over it without filler material and “reweld” it. The process smooths out the weld and helps it wet out. REVOLUTIONARY TREK!!!

Interesting that they are using hydroformed tubes but didn’t choose the aero tube shapes of the Madone design.

@Robert W – my sources say the Madone is on the way out. & if the story is about weight vs. areo it would make sense to mimick the emonda shapes. Also, the 2 series aluminum frames are already Madone-esqe.

I always find it funny that companies state how they’ve extensively optimized tube shapes for their flagship carbon fiber bikes, but then seemingly can successfully apply those shapes to materials with very different properties. There is a little marketing lie in their somewhere.

Anyway. Glad to see these Al bikes. CF has been getting too pricey fort me.

I like how they quote an unpainted frame weight, then only offer it in a painted variety. But lets also make sure we pair that unpainted weight with a painted fork weight.

Looks legit. Seeing they are coming out of the Giant factory why not put on the overdrive 2 fork and stem and really take it next level?

Aluminum, how quaint.

Why not sell them unpainted if they weight them unpainted? JBikes if I read you right what your saying is the shapes have far mo9re to do with design than engineering.all thes tube shapes are probaly coming from kitchen appliance design firm and they bs riders who rarely go over 20mph that aero is worth buying a new bike for

That Bontrager cycling kit is pretty damn nice. “Understated” as the hipsters like to say.

How about US made aluminum, with giant tubes, some internal routing, and some really funky paint jobs. Oh wait…

Hasn”t specialized already been doing this for like 3 years now? And better welded joints? Revolutionary-nothing is more like it, just another slightly modified copy frame.

Roy – no I was just commenting on the fact it’s stated how non aero tube shapes are optimized for carbon fiber for whatever properties (stiffness, weight, ride) but then a vastly different material can achieve the same with the same tube shapes? I’m sure they vary material thickness and such, but given the vast difference in CF and Al, I’d think tube shapes would vary more between the two materials, unless the CF and Al frames ride completely different.

Jesus, tough crowd. Lightweight aluminum, full component groups and small price tags… Sounds good to me.

Full Ultegra! Well… except the wheels. Of which, the Bontrager Race spec is a few notches below Ultegra…

y’all are haters. you can pick on the marketing and on random bits and pieces but in the end this is the bike you’re going to start seeing at all the local crits and races. So they have weird marketing, worry about the bike and what it can do for you.

Aluminum is the new carbon.

Yeah a bunch of haters here, Go buy a Specialized because they are not owned by the big man, Oh wait, Specialized is own by a conglomerate, and Trek is family owned. Seems like most people don’t understand the definition of “the man” Don’t hate on them just because you don’t like it that more people ride Trek than any other brand in the US.

@Durianrider, you’re killing me! Lol

When you think about it, it’s a bike people actually look for: Workhorse, and the no-nonsense but clean aesthetic.

Considering the Propel SLR might not come stateside, as well as the update TCR SLR before it, it’s nice to have another potential alloy option on the market that isn’t an Allez or CAAD.

I really like where Trek is going with their new paint schemes. Very minimal branding and no stupid racing stripes and decals. Keep it premium!

Jbikes: I understand why you’re asking about why two frames with different materials have the same tube shapes, but in fact they probably should have the same shapes.

In the bike industry (and many others), it’s common practice to design using isotropic material properties (e.g., with aluminum) for a first pass. The resulting stiffness (quantified through FEA) ensures you’re getting the most sectional modulus you can out of a given tube shape. Only then do you go back and design a laminate schedule with anisotropic materials (e.g., carbon fiber).

This allows the designer to clearly separate the modulus (stiffness) due to tube shape and the modulus due to the laminate schedule. That way, each can be optimized as a discrete step.

Except for a few corner cases, optimal frame tube shape is material-independent. Surprising but true!

Looks like a great bike at a good price. I love nice aluminum race bikes. But why no H1 geometry option? It irks me that companies (not just Trek) spec the really race oriented stuff at the high-end of the price scale. I know a short head tube doesn’t work for everyone but why not give us the option? What does the size of your wallet have to do with your flexibility?

I’m wondering if some of the frames are anodized, so unpainted weight would be pretty relevant.

JasonK – thanks! Great info. Never really thought of it that way but it makes sense.

I like the emonda and the CrossRip frame for my commuter. I would seriously consider if I was in the market and carbon was not an option.

Man that’s a light frame. Nice to see they are using full groupset specs.

I wonder if the welding is a form of aluminium brazing using a lower melting temperature brazing rod. I think this is what Shimano do with the external reinforcing tabs on the aluminium rims. This is supposed to be lower strength than welding but coming up with some newer technology is not beyond Trek’s resources. Or maybe they have come up with a way to modify the pulse action of a TIG welder with a certain filler wire application. Either way, the old double pass method for aluminium is old hat now.

Most companies claim unpainted frame weights. Use this general guide: If a company says “…painted frame weight is…” then it’s including paint. If they don’t specifically say painted then you can guarantee it’s an unpainted frame weight.

The only reason I wouldn’t buy one of these is the head tube is too tall…

I applaud Trek for coming out with a ‘light’ and ‘inexpensive’ aluminum frameset but I’m still not sold on the H2 geometry.

Sincerely, Worlds longest head tube.

I like the option of a high end aluminum frame as well….but this one misses the mark for me because trek refuses to make any bike with its “racer” H1 geometry that doesn’t cost at least 4,500 for a frameset. If they only would make H1 options of their emonda sl frame or this new all I’d buy one in a second. Trek already makes a million bike models….why not better fit options? Ever since they did away with the 6 series madone the options for the budget conscious racer have gone to zero. Bleh. And more seatmast length options trek!

Nearly the same weight as a Cannondale frame that was first manufactured out of the same material about 6 years ago

I think this will make a GREAT race frame.

Certainly beats trying to replace a carbon frame someone broke for you in that ‘last corner of the criterium’ crash.

If I see one more I’m-so-flexible-I-can-stick-my-head-up-my-ass comment about the lack of H1 geometry, I might give up trolling comments on bike rumor all together. Seriously, 5 years at a Trek dealer and we sold maybe 3 H1 bikes (all as special order). We ordered dozens more project 1 bikes in the ‘normal’ H2. Working now at a Cervelo dealer I have very few people balk at the head tube height, and MOST are running a positive angle on the stem anyways. At 6’3″ I run 14cm of bar drop. I have had zero issue getting a proper fit on stock bikes, including Trek. Currently on the newly updated (i.e. market norm) stack of the 2015 Cervelo S5 I still have 15mm of spacers under my stem. If H2 geo just doesn’t do it for you, grab a Cannonade with a low profile headset cap and go ride. They are making a bike for the largest market, obviously the budget racers this bike is designed for are too busy riding their bikes to complain on Bike Rumor…..

Looks like a great bike for the money and your avg rider. Nothing wrong with that. Kudos too for specing a complete group build, awesome!

Waiting for my ALR 5 to arrive!! Last bike I bought was in 1986, a Myata One Ten. Hopefully this one will last another 29 years.

uhhh… the allez actually looks good

http://www.specialized.com/us/en/bikes/road/allez/allez-comp-race

the only thing actually missing from these frames are some colorway options like the tarmacs

i had a domane and the headtube was too tall.

i might get one of these. its pretty affordable all things considered.

There doesn’t seem too much, if anything at all, to complain about here. The Emonda ALR frame MSRP is right in line with a CAAD10 frame MSRP ($10 cheaper actually). It looks good, and it’s certainly not a heavyweight bike. If it rides as good as it looks, it will be a great deal.

@MikeC – Are you kidding? I haven’t seen anyone refer to a full groupset as including the wheel since like 1999. Some people are just desperate to find something to bitch about. The Bontrager Race wheels are great. They only weigh 200g more than the Ultegras, and unlike every Shimano wheel, they are specced completely with off-the-shelf parts that are easily purchasable in any bike shop.

@Adam – Yes, because Cannondale were the first company with an aluminum racing bike. You forget the Trek, via Klein, were making awesome lightweight aluminum race bikes when Cannondale was still welding together soda cans.

@H1 Lovers – You’re all on crack. A quarter of the Trek pros don’t even ride the H1, and I promise you that you are not that fast. I can also tick off a list of local heroes, Cat 1 and PRO dudes, who get by just fine on the H2, usually preferring it to the H1.

@Psi – And the Trek is clearly much better specced than the Cannondale, with an Ultegra crank and Bontrager Race wheels, not to mention a cockpit that won’t require immediate replacement.

Wait to you see the next gen cannondale frame before you jump on this..

I am happy this exists. Buyers beware if you crash this thing it’s probably going to dent up like tinfoil.

@badbikemechanic – What makes you say that? There is a generation of high end aluminum out there that holds up just fine to the rigors of daily life. I personally have an aluminum Allez that I regularly leave locked up outside of bars, the grocery store, as well as race, and it hasn’t even scratched the anodized finish yet.

As always, opinions abound….and everyone is “right.” The H1 vs. H2 debate is clearly a hotter topic than I thought. What it boils down to though is “choice.”

Trek offers the option, meaning there are people that prefer it. I rode a 60 cm H1 Madone 6 series last year, and absolutely loved it. Sadly it was a team bike and I had to give it back at the end of the year. In looking for a replacement I want a bike with similar geometry, but don’t want to spend 4,500 to have the OPTION to get the geometry I like. The head tube on the H1 is 18 cm…compared with 21 cm on the H2. That is a LARGE difference. I don’t think anyone is right or wrong to ride whatever geometry they like. All I’m saying is that for me…the H1 geometry is perfect, and I don’t need to run a -17 stem to get my preferred position of the bike. Being a pro, being fast or slow, is irrelevant. I would just like to see the option available at a reasonable price point.

These bikes are epic. And yes, they blow the competition out of the water.

About time Trek offers something for the Joe-Racers out there. Yes, carbon is super nice but you guess what: so is aluminum. I have a locally-made Aluminum bike and it rides *amazing*. So did my old Caad7 and I bet Specialized’s aluminum bike is also fantastic. We need more people in the sport, and to do that we need a much lower entry-level bar. if for $2,200 you get a nice Al Trek with good geometry, good wheels (i own the bontis tlr and they’re indestructible and readily serviceable), good parts and cockpit that are either race-ready or hammer-ready, then god bless Trek. For the record i own a cannondale six and it’s a phenomenal bike. but my aluminum rig is my favorite. way to go, Trek – kudos indeed.

Arguing that “some pros ride H2, therefore nobody needs H1” is well, just a poor excuse for an argument. An H1 aluminum Emonda would be a hit, and I would purchase one as soon as it were available. I’ve owned and ridden both H1/H2 models, and greatly prefer the H1. As an aside, direct mount breaks on this beast would be the icing on the cake. Think about it Trek.

This bike compared with the new caad 12 is nothing …

I’ve got a current model year Allez smartweld frame built up with full 105 and tubeless Shimano wheels. I certainly didn’t do it for $1760 retail, but then some parts on my bike (bars, saddle, tires) are from a very much higher trim level. I’ve also got all the accessories (cages, tools, &c) in my price, and I was unable to use the economy of scale a manufacturer can.

ANYWAY. The ride quality of my Allez is nothing short of amazing considering. It is *as smooth* as my steel 3-speed with 38mm tires over brick roads. I have no problems riding the Allez a hundred miles, though I run out of water. The Allez smartweld is making me completely re-think aluminum as a frame material, especially for amateur racer types.

These Treks seem to DIRECTLY compete with the Allez smartweld introduced last year, which is great, since it engenders competitive designs. When you get an Allez Comp (with 105), you pay less, but you miss out on the excellent 5800 brakes and crankset, and get bog standard training wheels. Moving up to an Allez Expert (with Ultegra), gets you a full groupset with carbon SL-K crank and ‘Fulcrum’ wheels at a competitive price.

I’d love to ride these Treks back to back with my Allez.

I am happy to see Trek jump into the “high end” aluminum market. I have owned & loved several iterations of CAAD’s. I have also read good things about Specialized redesigned Allez frames. I am now hearing of a redesigned CAAD12(?) to be released later this Summer…(anyone else hearing any details?) I would have liked to have seen a disc version from Trek… (Spec as well.) I believe that road disc offerings from every manufacturer will increase exponentially once the pro’s are riding them. I wanted my next road bike purchase to have discs so that I can look for second set of wheels that will be future proof…(thru-axles coming next?) I had my eye this year’s CAAD10 Rival disc, hoping the boys at Cannondale offer an Ultegra disc spec on the CAAD12 later this year. 🙂

Just ordered my alr 6 today! I work at a trek dealer, and I have to say H2 is usually great for 99% of our customers, and they usually have the stem flipped up. For the 1% of people that actually want that huge bar drop, you can always size down and make it look super pro with a longer stem! Nothing wrong with that!
