When Trek first introduced the Émonda back in 2014, it was sort of a surprising addition. Seeming to compete directly with the Madone, the biggest difference was that Trek’s new lightweight lacked the aerodynamic touches of its sibling. Now with the most modern iteration of the Madone, we know that Trek was already working on creating …

In developing the Émonda, Trek devoted considerable resources to designing a lightweight race bike and trumped the industry with a 690g frame.

What Trek Émonda is Right for You?

The Trek Émonda has always been a climbing bike — if you love epic hauls up huge hills, this lightweight, stiff road bike was made for you. The Émonda was created with the steepest grades in mind. Over the years, Trek evolved its patented Optimum Compaction Low Void (OCLV) carbon fiber to combine low weight and high strength.

The carbon  Émonda is  available in the superlight SLR build or SL, which is more affordable. The difference is the quality of the carbon, and thus overall weight. The Émonda also comes in an aluminum version (ALR). Finally, you can choose between two geometry options, H1 — an aggressive race fit — and H2, which is a more upright relaxed fit.

The Émonda is known for its neat and tidy look. Models with Trek’s Blendr Integration components allow riders to mount a cycling computer and bike lights directly to the handlebars. On the SLR version, shifter and brake cables are entirely housed inside the frame. SHOP TREK ROAD BIKES

History of the Trek Émonda

Émonder, in French, means “to prune,” which is fitting. Introduced in 2014, the Émonda was Trek’s pure climbing bike. Trek trimmed off as much as possible to create an incredibly lightweight racing machine. Newer versions have been designed to better handle mixed terrain, with clearance for wider tires and aero features. When it launched, this road bike was only available with rim brakes. But soon after, disc brakes were added for better control on descents.

As the bike evolved, we saw fewer exposed cables, more integration, and better aerodynamics. Despite the fact that this is a climbing bike, Trek spent a lot of time optimizing the shape of the head tube, down tube and bar/stem. Émonda timeline: 2015-2017:  From the beginning, Trek's focus was on creating a light, stiff road bike that excelled in the mountains. Its engineers spent years developing the  Émonda to be the lightest production race frame on the market. In 2016, Trek introduced internal cables and Di2 shifting on the  Émonda . It also unveiled the affordable aluminum ALR model using Ultralight 300 Series Alpha Aluminum.

2018-2020:  The second generation  Émonda  was introduced for the 2018 model year. Trek announced a new disc brake version alongside a revamped rim-brake model.   Claimed weight for the new disc-specific frame was 25g lighter than the previous-generation rim-brake  Émonda . The new rim-brake version was even lighter still, dropping another 25g. Tire clearance increased to 28mm. 

2021+: Instead of making the Émonda even lighter, Trek focused on making the third generation faster on any terrain. Trek integrated several aerodynamic features to help this bike perform as an all-rounder. It also added a T47 bottom bracket, which is threaded instead of press fit, generally a more reliable standard. The new  Émonda  is disc brake only.

Trek émonda slr 8 road bike - 2016.

Trek Émonda SLR 9 road bike - 2018

In keeping with tradition, Trek released the SLR 9 just days before the Tour de France. And as always, it was a little lighter than before. This time, the 700 Series OCLV Carbon frame came with Bontrager Aeolus 3 D3 tubeless ready carbon wheels, and a full Shimano Dura-Ace Di2 electronic drivetrain.

Trek Émonda SLR Race Shop Limited road bike - 2018

For this model, Trek used its Ultralight 700 Series OCLV Carbon, ride-tuned performance tube optimization, E2 tapered head tube, direct mount brakes, and internal cable routing. This model comes with Shimano Dura-Ace Di2 shifting, Bontrager Aeolus 3 TLR carbon clinchers, a Bontrager cockpit and Montrose PRO saddle.

Trek Émonda SLR Disc Project One road bike - 2019

Project One allowed riders to customize several details. You picked your paint and parts, making each one of these bikes unique. There were options for Shimano Dura-Ace Di2, Ultegra Di2, SRAM Red eTap AXS, Force eTap AXS, and Rival eTap AXS. And about 20 different color schemes.

Trek Émonda ALR 4 H2 road bike - 2021

The ALR is Trek’s budget-friendly high-performance model — its lightest aluminum road bike that handles and climbs very much like its carbon counterparts. With the H2 geometry, it’s perfect for a more upright, less aggressive fit. It comes with tubeless compatible wheels, and a lifetime warranty.

The newest Émonda SLR frame weighs less than 700g, and with all-new aero tube shaping adds even more speed. But with ALR and SL models, H1 and H2 geometry, and a huge variety of specifications to choose from, there’s an Émonda out there for absolutely anyone who loves to climb up hills and then fly back down.

Trek likes to keep it simple, stupid when it comes to navigating its road bike range. Madone: that's the aero one. Domane: that's the comfort one. Emonda: that's the lightweight one. Easy-peasy.

The Emondas are then divided up into the aluminium ALR and the S, SL and SLR carbon fibre frame platforms, getting progressively lighter and – because this is the way things generally work – more expensive.

Coming in at 8.55kg (18.8lb), the Emonda SL 5 is light but it doesn't feel like Trek has filled the tubes with helium (the frame weight is a claimed 1,091g, size 56cm). The Merlin Nitro SL (£200 more expensive at £1,999.99) that we reviewed back in the summer hit the scales at 7.7kg (17.0lb), for instance, while the Boardman SLR Endurance Disc 9.0 (also £1,999.99) we tested was 8.2kg (18.2lb).

Don't get too hung up on weight, though. I only really bring it up because Trek makes such a big deal of it when talking about the Emonda. Climb aboard the SL 5 and it immediately feels alive, responding keenly as soon as you turn the pedals. Put a serious amount of power through the cranks and it springs forward as if it was just waiting for the flag to drop. Both the head tube and the down tube are enormous, holding the frame firmly in shape when you're recruiting every muscle fibre on an out-of-the saddle sprint or climb.

Relaxed but performance-orientated

Speaking of climbing, the Emonda SL 5 is fitted with a Shimano 105 compact chainset (50/34-tooth chainrings) which, matched to an 11-28 11-speed cassette, provides enough low gears to get you up the steep stuff in relative comfort. All of the other Emonda SLs are fitted with compact chainsets too, by the way, and they all come with frames built to Trek's H2 fit. That requires an explanation and, as luck would have it, there's one coming along right now... While Trek's H1 fit puts you into a low, flat-backed, aggressive riding position, H2 is a little more relaxed, although it's still performance orientated.

I have the 58cm Emonda SL 5 here with a 57.3cm effective top tube, a 55.3cm seat tube and a 19cm head tube. The stack height is 596mm and the reach is 391mm.

With an H1 fit (the Emonda SLR Race Shop Limited frameset is available in H1) the reach is a little longer (400mm) and the stack is quite a lot lower (567mm). You all know what reach and stack are... (no? stack is the vertical and reach the horizontal measurements from the centre of the bottom bracket to the top of the head tube).

Don't get the impression that the Emonda SL 5's H2 fit will have you sitting bolt upright in the saddle because it's a long, long way from that. For comparison, a 58cm Domane SL 5 has a stack height that's 15mm higher and a reach that's 11mm shorter. In other words, the H2 fit sits somewhere in the middle, an Aristotelian golden mean. Or Goldilocks' favourite porridge, if that's a cultural reference that works better for you. Put simply, a lot of people will get on well with the fit because it requires less flex in the back and neck than a traditional race fit without binning off the idea of efficiency.

One aspect of the Emonda SL 5's ride that surprised me is the level of comfort on offer here, particularly for a performance bike with 25mm-wide tyres. Okay, you don't get a clever IsoSpeed decoupler like you'll find on a Madone or a Domane to cushion the ride, but there's a decent amount of give in the seatmast and cap that Trek provides instead of a more traditional seatpost, and in the flattened, ultra-skinny seatstays.

As we all know, saddles always come down to personal preference – what feels like an armchair to one person can feel like a razor blade to another – but the steel-railed Bontrager Montrose Comp specced here has a pressure-relief channel/hole in the centre and loads of flex in the shell so I imagine it'll make more friends than enemies.

Great groupset

The Emonda SL 5 descends with assurance, giving you the confidence to lay off the brakes when others are nervously feathering theirs. When you do need to slow down the Shimano 105 brakes work on the alloy rims to provide plenty of predictable power. Shimano does make very good brakes. These are of the direct mount variety and they can be relied upon to hold tight when you need them. They even put in a decent performance in damp conditions although, like any rim brakes, they're outperformed by disc brakes when it's properly wet. If that bothers you and you can stretch to £2,650, the Emonda SL 6 is available in a disc version – with 12mm thru-axles front and rear, a Shimano Ultegra groupset including flat mount hydraulic discs, and an 11-32t cassette.

As well as the brakes, the SL5's shifters, derailleurs, chainset, cassette and chain are all Shimano 105. We've covered this groupset a million times on road.cc and it really is difficult to fault for the money.

I particularly like the light action shifters. They're slim, comfortable and easy to operate from either the hoods or the drops. There's not a massive difference between these and more expensive Ultegra, or even top of the pile Dura-Ace mechanical shifters. Sure, you can tell them apart but in use... puh! I'd happily use 105 on every ride. It's amazingly popular and rightly so. Although a couple of others run it close, 105 is still arguably the best value groupset out there.

> Head to head: Shimano 105 vs Shimano Ultegra

> And: Shimano Tiagra vs Shimano 105

This has all been a bit of a lovefest so far, but my one tiff with the Emonda SL 5 was right at the start of our relationship. I picked up the bike and was riding home from the office on it – five miles in, whistling a happy tune, thinking about what I'd have for tea, you know the sort of thing – and the front end started to feel... odd. I got out of the saddle on a climb and it felt decidedly spongy. Weird!

I stopped to check everything and it turned out that several spokes had loosened – about eight of them, I think. And I mean that they'd really loosened to the point that the nipples were just about holding on by their fingertips (shut up! Of course they do). My multi-tool has a spoke wrench on it so I tightened them up at the side of the road, then did a proper job when I got home. Since then the wheel has been fine.

I've reviewed loads of Treks before and this hasn't been an issue in the past, so I'm happy to put it down to bad luck. To be honest, if you know which way up to hold a spoke wrench it's not a massive problem, but it would be a pain if you had to book your bike in to a shop and have a mechanic do the fettling for you. Anyway, I've forgiven the Emonda SL 5 for that now and we've both moved on.

Spoilt for choice

The Emonda range is large, kicking off with the Shimano Tiagra-equipped ALR 4 at £1,000 and going right up to the SLR 9, with Shimano Dura-Ace Di2 components, at £8,500 (a customisable Project One version of the Emonda SLR 9 is also available).

There are four SL models ranging in price from £1,500 (SL 4, Shimano Tiagra) up to £4,300 (SL 7, Shimano Ultegra Di2). At £2,000, the Emonda ALR 6, with an aluminium frame, is actually more expensive than the SL 5 courtesy of a next-level-up Shimano Ultegra groupset. The SL 5 is also available as a women's model.

Oh, and you can buy an Emonda SL frameset for £1,350 – but why would you do that when you can get a complete Emonda SL 4 for £1,500?

> Check out our guide to Trek's 2018 road bike range here

As well as the Emonda SL 6 Disc mentioned earlier, there's an Emonda SL 7 Disc, equipped with a Shimano Ultegra Di2 groupset and Bontrager Aeolus Pro 3 Tubeless Ready wheels, for £4,400.

You can certainly get complete bikes with carbon fibre frames and Shimano 105 components considerably cheaper than the Emonda SL. The Focus Izalco Race Carbon 105, for example, is £1,399 and Giant's TCR Advanced 2 is £1,449. Those two are killer value. Equally, there are plenty of carbon/105 bikes out there that are more expensive. Cervelo's R2 105 is £2,199, for example, and BMC's Teammachine SLR02 Two is £2,250.

I would say that you're getting an extraordinarily good frame with the Trek Emonda SL 5 – one that'll handle considerable upgrading if you fancy doing that gradually as and when individual components wear out. It's that which makes this bike such impressive value for money.

Overall, the Trek Emonda SL 5 is excellent. I had an early issue with one of the wheels but that doesn't detract from the fact that this is a fast and nimble road bike that reacts like something considerably more expensive. Also comfortable and well behaved, it makes you question whether it's worth spending any more money than this.

Tell us what the bike is for

It's a road bike designed for racers and other performance-type riders who are interested in speed and fitness.

Frame and fork

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

The quality is exceptionally good throughout.

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

The frame is made from Trek's 500 Series OCLV carbon fibre. The fork is carbon too.

Tell us about the geometry of the frame and fork?

Like all the Emonda SL frames, this bike is built to Trek's H2 geometry which sits somewhere between a low and stretched H1 fit and a more upright endurance setup. H2 is certainly performance-focused, it's just not as aggressive as H1.

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

It's about what you'd expect.

Riding the bike

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

It's surprisingly comfortable for a bike of this type. You only get so much cushioning from 25mm tyres but the seatmast certainly helps to damp vibration and soften the blows.

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

The super-wide down tube holds the bottom bracket firmly in place and the tapered (1 1/8in to 1 1/2in) head tube keeps the front end in order.

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

It felt efficient, without a doubt.

Was there any toe-clip overlap with the front wheel? If so

Some. It's only ever an issue for tight manoeuvres at walking pace.

How would you describe the steering? Was it lively Lively.

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

It offers a great ride whether you're going uphill, downhill or on the flat. It's a well-balanced bike that feels like it can cope with pretty much anything.

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

The seatmast and seatmast cap take some of the credit here, along with Bontrager's saddle.

You can swap to 28mm wide tyres if you want to run lower pressures for more comfort.

The drivetrain

Wheels and tyres

I have to take into account that several spokes came loose almost immediately. The rims are tubeless ready, if you want to go down that route.

After an initial scare they were fine.

Anything else you want to say about the componentry? Comment on any other components (good or bad)

The Shimano 105 groupset put in an excellent performance.

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

Use this box to explain your overall score

The Trek Emonda SL 5 puts in a really strong performance. You'd be hard-pressed to tell from riding it alone that this wasn't a considerably more expensive bike. You're getting an exceptionally good bike for the money, and that equates to a 9.

I share similar thoughts on Emonda SL 5. Bought new in 2019 as 2018 model for only 1.200 € and it seemed like a great deal. But wheels almost fell appart after 30 km, most of the spokes were totaly loosened. I was lucky to find that out just before the fast descent. Both wheels, front and rear! I took it to dealer and they said I was just unlucky, one in a million. Then I waited more than 2 months for new pair of wheels, replaced under guarantee. Got Bontrager Affinity TLR wheels. They were fine but bearings seem to be totaly destroyed after about 7000 km. So I did upgrade to Mavic Cosmic.

What do I think about the bike now? It is a great bike, with perfect geometry for me, very responsive and good for climbing. Not super light but good enough. Not aero at all but new wheels are doing the job much much better. It's a climber not a TT bike. Would I recommend the bike to anybody? Probably not, due to the serious issue with wheels that could affect safety. 

I still cannot understand how can a company like Trek put so awfull wheels on a nice carbon bike like Emonda 5. In my eyes this was a recall situation and obviously not a one in a million case.

I might be corrected but up to last year or perhaps this, the model was fitted with lighter 'Race' wheels.  They kept the price at £1800 and put cheaper wheels on it.  It's a shame as the frame and groupset is excellent, in my opinion.

  "Coming in at 8.55kg (18.8lb), the Emonda SL 5 is light...

   Don't get too hung up on weight, though. I only really bring it up because Trek makes such a big         deal of it when talking about the Emonda".

How does a carbon bike which sells for £1800 and weighs over eight and a half kilos get described as LIGHT ?

For comparison at £1800:  the Canyon Endurace CF8.0 is size Medium is 7.2 kilos.

The £1800 Rose GF Team 4 Ultegra is 7.1 kilos.

Both bikes have a complete Ultegra groupset - no sneaky substitutions, both have excellent DT Swiss wheels and are well equipped right down to Conti's top tyres.

What they seem to lack (apart from a kilo and a half) is the word Trek written down the side.

If the original article was from 2014 when the SL5 was launched, then 8.55 Kg would have been viewed as somewhat light for a fast endurance bike back then.

"If the original article was from 2014 when the SL5 was launched, then 8.55 Kg would have been viewed as somewhat light for a fast endurance bike back then".

     All true, although the article is bylined:

                   by Mat Brett May 25 2018  

    and a quick check of the Evans website suggests the bike is still nearly eight and a half kilos.

Unlike the German bikes this bike does come with boat anchors for wheels and wire bead tyres. Along with the 105 groupset that would explain most of the weight difference.

The review suggests though that the frame is fantatsic so a wheel + tyre upgrade would leave you wth a fantastic bike. Sure it would cost more than the German bikes but there's more to a bike than just it's weight.

European reviews of the Rose & UK and European reviews of the Canyon suggest the frames on both those bikes are excellent too. So the question is: do you want a lightweight bike with an excellent frame, a complete Ultegra groupset, highly regarded DT Swiss wheels and top drawer finishing kit... or do you want the Trek.

Or you could take the view that a bike is more than just a frame, a groupset, wheels, tyres and finishing kit in which case the big American brands with their overweight, under specced and overpriced offerings are for you.

"Updated May 25th  2018". It was a recycled article, hence my comment......

Why is this bike being compared to the  Boardman SLR Endurance Disc 9.0? The calliper version comes in at 7.6kg and gives you an almost complete Dura-Ace groupset and a better wheelset for only £99 more.  https://www.boardmanbikes.com/gb_en/products/242-slr-9.2-endurance.html

Did a few hundred KMs on a rented SL5 in Mallorca earlier this year.

Nice machine, although the most impressive element was the 105 groupset (especially the brakes), which is easy to find on other makes/models.

It was definitely comfortable, and reasonably light - although I couldn't say I noticed a huge improvement on my 725-framed Equilibrium. May be my own frame which means a couple of KG off the bike doesn't make much obvious difference, of course...

So certainly not a bad option but I'd be tempted to look around a bit more before splashing that sort of cash.

Decent / good frame with full 105, own brand everything else (bars, stem, seatpost, wheels, tyres, may be ok stuff) inc wheels which look very spokey. 

giant tcr advanced pro 2 would be a potentially better bike

in a sale at £1800 it has giant tcr frame (one of stiffest on market) giant slr carbon wheels and 105.

beaut bike would reccomend. Its weight is also 7kg

Well that's very reassuring.

Incredibly generous considering the wheel supplied was in a dangerous condition.

An ordinary person may not have noticed the odd feeling and ridden it until it collapsed under them, throwing them under a car. It’s pretty serious.

Well that really depends, for most people that would have been picked up by the shop you purchased the bike from. For everyone who orders it direct I would expect them to check the wheel before riding it

Really? They'd notice the wheel not fitting between the brake pads a long time before collapsing.

We introduce the concept of para-Hopf algebroid and define their cyclic cohomology in the spirit of Connes–Moscovici cyclic cohomology for Hopf algebras. Para-Hopf algebroids are closely related to, but different from, Hopf algebroids. Their definition is motivated by attempting to define a cyclic cohomology theory for Hopf algebroids in general. We show that many of Hopf algebraic structures, including the Connes–Moscovici algebra \({\cal H}_{FM}\) , are para-Hopf algebroids
