Examined: 2021 Emonda From Trek – Bicycling Australia

Tested: 2021 Emonda From Trek - Bicycling Australia

By Gordon Haywood & Nat Bromhead | 16 October 2020

Essentially the most disrupted yr in many years, not loads has gone to plan in 2020. WorldTour racing stopped, commerce exhibits had been postponed and even membership racing got here to a whole standstill. However the main producers are nonetheless releasing vital new fashions as we see right here.

With three premium street choices – the Emonda, Domane and Madone – Trek’s product cycle for his or her climbing, endurance and aero platforms is three years. So, you don’t should be a maths wiz to work out that every yr one mannequin of this triumvirate of Treks enjoys a good quantity of additional consideration.

It may simply be argued {that a} three yr product cycle is sensible in some ways. It treats patrons and house owners with extra respect, recognises the funding put into a brand new bike and permits time for real and vital technological advances and enhancements.

Cable free and all about aero & effectivity – the 2021 Emonda from Trek.

A light-weight climbing bike, the brand new Trek Emonda was to be launched at legendary Alp d’ Huez and in time for the Tour de France. COVID-19 modified that, as a substitute the bike was offered to the world through an progressive digital debut.

…it actually is essentially the most spectacular all rounder and specialist climbing bike we’ve ridden…

An informative and interactive hour-long presentation was made through a closed YouTube channel. Just a few partially sleepless nights later, we picked up a top-of-the-range check rig from a dodgy automotive park in Mona Vale north of Sydney.

Gleaming in Trek’s Challenge One ‘Amplified Alchemy’ color scheme, the bike actually appeared quick standing nonetheless. A variation of the oil slick colourway, iridescent blue on the lead fringe of the fork seamlessly morphed into purples, blacks and golds by the frameset, as if mimicking the sculpted aero shaping clearly apparent from entrance to rear.

Lightest Emonda But

A real superbike (and with a pricetag to match – extra about that little later), one of many first stuff you’ll discover concerning the new Emonda is its headline function of it’s sub 7kg general mass. In measurement 56 and fitted with the brand new top-level Aeolus RSL 37 TLR wheels, the brand new Emonda pulls the scales to six.75kg.

Mixing a light-weight construct with a very aerodynamic frameset is a troublesome steadiness for any producer. It wasn’t that way back that aero body design got here at a price … that being weight. However much less is extra, as they are saying, and this does look like the case with the third incarnation of this purist’s climbing bike.

The check bike was completed in a blinding ‘Amplified Alchemy’ color approach.

Beginning with the brand new Aeolous wheel set, to the fork, steerer, handlebars, prime and down tube shaping, proper by to the seat put up and rear triangle, each fringe of the Emonda has been designed with aero in thoughts.

In evaluating the bike to its predecessor and through testing, Trek measured the brand new Émonda SLR as 60 seconds per hour quicker on flat roads and 18 seconds per hour quicker when climbing an 8% grade.

That was clearly in managed testing, however how does it translate to the street?

In a phrase … quick. This can be a bike that accelerates arduous, eats up undulations and actually holds its velocity. Get it on a climb and that sub 7kg construct weight comes into its personal – my solely grievance right here was commonly lifting the entrance wheel off the street on a very steep Northern Seashores ‘berg.

The place’s The Weight?

Changing OCLV (Optimum Carbon Low Void) 700, the newest Emonda relies on an OCLV 800 carbon frameset for a sub-700g body with the fork weighing in at 365 grams (lower than a can of beer).

To the wheels and the aforementioned Aeolus RSL (Race Store Restricted) 37mm TLR (tubeless prepared) aero wheel set pulls the scales all the way down to a teeny 1,325 grams.

Additional weight saving and aero positive factors are made through a brand new built-in handlebar design, the Aeolus carbon 1-piece bar / stem consists of hidden cable routing for a slick and quick end.

One space the load is just not saved is within the brakes – the brand new Émonda is offered in disc brake solely construct.

The brand new Aeolus RSL37 wheels.

How Does It Deal with?

Out on the street and also you would possibly assume this stiff and aero weight weeny would bounce alongside like a inflexible little sizzling hatch. With 90psi by the tan wall Bontrager Laborious Case Lite R3 tyres (200grams in 25c), the experience was surprisingly forgiving.

Retaining the standard body design and electing to not decrease the seat stays (like nearly each different new bike), Trek say this assists with general compliance and luxury. The chain stays are additionally thicker when in comparison with many different fashions – and the seat put up extends above the highest tube
once more aiding consolation.

It’s not #1 as far as the most effective dealing with bike Bicycling Australia have examined over the previous few years, the Merckx EM 525 will get that gong, however the Emonda is true up there as 2nd or third. That stated, given its confidence round corners, its stiffness with a lot due to a beefy backside bracket, it actually is essentially the most spectacular all rounder and specialist climbing bike
we’ve ridden.

Whereas on the subject of the underside bracket – and Trek have performed away with the outdated BB90 press-fit design. In place is the T47 threaded shell that’s approach much less prone to creak and loads simpler to service and preserve – a sensible transfer all spherical.

Along with launching the brand new Emonda, Trek have launched an up to date Domane that includes the identical OCLV 800 carbon for an general weight saving of 450grams. And that T47 BB can be fitted to the Domane.

In launching the brand new Emonda Trek launched an built-in bar/stem system as seen right here.

Shedding general weight isn’t all within the carbon combine, a brand new wheelset often known as the Aeolus RSL 37’s even have a good bit
to do with it.

…The wheels function the legendary DT Swiss 240 hubs and can spin you into the subsequent suburb…

Focusing on a broad part of the market, the vary of carbon disc hoops embrace 37 to 50mm rim depths ranging in value from $1500 by to round $3700 for every wheelset, with accessible fashions together with the RSL 37, Professional 37, Elite 35 and the Elite 50.

The highest-end RSL 37mm tubeless-ready wheelset as fitted to an SLR 9 Emonda. The cream of the crop, that is as high-end as you may get. After a number of native rides on lengthy flats, medium-length climbs and brief, sharp hills, these wheels are proper up there with the most effective from Zipp, ENVE and different premium producers.

They function the legendary DT Swiss 240 hubs and can spin you into the subsequent suburb. These wheels are noticeably quicker and extra environment friendly than every other wheels we have not too long ago ridden. This interprets to smoother and higher rolling, a trait that was particulalry noticable on the shorter, punchier native climbs.

The bike comes manufacturing facility fitted with 25mm tyres however will accomodate as much as 30.

RSL 37 Wheels by Gordon Haywood

It’s not usually our readers write to rave a couple of new wheelset, however we acquired the next out of the blue evaluation from Gordon Haywood.

‘I not too long ago took a 2020 Domane SLR 7 for a 100km experience over a spread of roads, surfaces, hills and descents. The aim? To type an impression of the brand new RSL 37 wheels.

A part of the experience included 2km of tarmac with bigger combination within the floor, my earlier Strava PR for this phase was 4:45. With the brand new wheels I did it in 4:29 … it was as if the floor had been crammed in, the lumps and bumps eliminated.


The DTSwiss 240s hubs with Ratchet EXP 36-point engagement made for a silent experience. On a shared path I didn’t want a bell, these rear hubs are noisy!


The lighter weight is actually noticeable when climbing at speeds above 20 km/h. The wheels are simpler to show with their decrease rotatonal mass, however 15% continues to be 15%. They wont flip me right into a Richie Porte however they do give me extra from my biking.


The obvious distinction with the RSL 37 is the moment suggestions in route modifications, and choosing a line and it stays there. There was some slight understeer with my older wheels above 50 kmh – that simply isn’t there with the RSL 37. They observe the road and encourage confidence.

Common Driving Velocity

Strava confirmed that I used to be on the prime finish of my quickest instances on most segments. For essentially the most half I rode in a smaller cog on the cassette (eg 19t reasonably than 21t), or I used to be spinning quicker – the typical cadence for the experience was up 2RPM. So as to add to the velocity / aero dialogue the RSL 37 have a particular profit above 20 kmh, more-so the quicker you experience. This profit was price not less than two enamel on the cassette.

Driving within the Wind

Cross winds had no vital influence on the RSL 37 – my notion was the RSL 37 wheels had been much less impacted and extra aero.


On the finish of a 100km experience, and little bit of it into an honest headwind, and me driving at 47% tempo and 43% threshold. I used to be drained. Nonetheless the graceful experience has resulted in noticeably much less shoulder ache and much larger effectivity.

The wheels have modified the texture of the Domane for the higher. It’s quicker, smoother, much less tiring to experience. Now I must re-learn how you can get the most effective from it.
