It's right for you if...
You love to fly up climbs, ride off the front and win every sprint. You want the lightest, fastest road bike we make, plus the performance advantage of a wireless electronic Di2 drivetrain's quick, precise shifting.
The tech you get
An ultra-light and aerodynamic 800 Series OCLV Carbon frame that weighs under 700 grams, a full carbon fork, a wireless 2x12 Shimano Ultegra Di2 electronic drivetrain, lightweight Bontrager Aeolus Pro 37 OCLV Carbon tubeless-ready wheels, an Aeolus RSL OCLV Carbon integrated aero bar/stem and powerful hydraulic disc brakes.
The final word
This bike flies up any climb. It’s aerodynamic for more free speed, but doesn’t sacrifice the amazing lightweight ride quality that Émonda is known for. It also has a Di2 wireless electronic drivetrain so you'll never miss a shift again.
The Walkthrough
favorite_borderWhy you'll love it
- Trek’s fastest climbing bike is aero, weighs in at less than 700 g, and rides like a dream
- The Wireless Ultegra Di2 delivers ever faster, smoother and more responsive shifts than ever
- 800 Series OCLV Carbon is the lightest laminate we’ve ever made
- Aerodynamic tube shaping makes this our fastest Émonda SLR platform ever – on flats and climbs alike
- The Aeolus Pro 37 wheels are designed for climbing, and were developed alongside Émonda
Features
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.
Outstanding bikes for everyone
Every rider – regardless of gender, body type, riding style or ability – deserves a great bike. The all-new Émonda is equipped with size-specific components that deliver a great fit to competitive riders of all genders.

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.
