All Winner 2021 Road Bikes
'The road bike generates propulsion and speed in every situation, shines with its aerodynamic performance and snappy race feel when attacking, and climbs fleetly up hills. With a riding position worthy of the pro peloton, the handling is razor-sharp and extremely precise, letting the Émonda be controlled on even the fastest of descents.'

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

'It's an incredible update from Trek.'
'The updated Emonda packs one hell of a punch, and Trek has a winner on its hands. The integrated cockpit is nice and all, but the real win is the H1.5 fit, which makes the Emonda feel more stable while maintaining the aggression and responsiveness of previous Emondas. That, coupled with a lightweight construction, comfortable ride and aerodynamic shaping, brings Trek's top-of-the-line climber from a very good bike to an excellent one.'

'The Emonda is still light, and it’s still stiff, but now there’s an extra dose of free speed.'
'Overall, Trek has done a solid job here of updating the Emonda, infusing meaningful improvements in several key areas, but without breaking the basic formula that has made the bike so popular.'

Faster on climbs, faster on the flats. The aero tube shapes on the all-new Émonda give you an advantage wherever you’re riding. Plus, Émonda SLR is equipped with a sleek new Aeolus RSL bar/stem for front-end aero performance.

It takes more material to make aero shapes, but we refused to compromise on weight – so we developed the all-new 800 Series OCLV Carbon for Émonda SLR.

H1.5 Fit
H1.5 geometry, developed with Trek-Segafredo pro cycling teams, puts the rider in the optimal aero race position. It’s the sweet spot for what our racers want.
Ride Tuned seatmast
Our no-cut Ride Tuned seatmast is designed for the rigours of pro racing. It's the lightest, most comfortable solution for day-in, day-out performance and comfort, however rough the roads or hard the riding.
Flat Mount disc brakes
All-new Flat Mount disc brakes are more elegant, lighter, smaller and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.
12mm thru-axle
Our robust and confidence-inspiring rear through axle is about 35% stiffer than an open dropout design. And now, a through-axle wheel change is actually quick and easy, thanks to a tabbed guide in the frame's dropout.
DuoTrap S compatible
DuoTrap S (sold separately) integrates a Bluetooth®/ANT+ sensor into the frame. Log routes and track fitness progress on your computer or smart phone with no external sensor. Works with all major ANT+ wireless players, including Bontrager, Garmin, PowerTap, and SRM.
