Emonda SLR 9 Disc is an ultralight, aerodynamic carbon road bike that's designed and built to be the fastest climbing bike we've ever made. You get the legendary ride quality of our lightest platform, plus more speed, thanks to aero tubes wrought from our lightest OCLV layup ever. Shimano's highest-end electronic drivetrain and our best climbing wheels give you every edge against the competition.

It's right for you if...
Great is for everyone else. You want the best, just like the pros of Trek-Segafredo, and that's our lightest, fastest road bike ever, stacked with tech that delivers an incredible difference in performance.

The tech you get
An ultralight and aerodynamic 800 Series OCLV Carbon frame that weighs under 700 grams, a 2x11 Dura-Ace Di2 electronic drivetrain, ultralight, fast, and stable Bontrager Aeolus RSL 37 OCLV Carbon tubeless ready wheels, an Aeolus RSL OCLV Carbon integrated aero bar/stem, and powerful hydraulic disc brakes.

The final word
Everything about this bike is ultralight and ultra fast, from the aero frame to the carbon wheels, to the precise, reliable shifting of the Dura-Ace Di2 drivetrain.

Why you'll love it
- Trek’s fastest climbing bike is aero, weighs in at less than 700g, and rides like a dream
- The Shimano Dura-Ace Di2 electronic drivetrain delivers lightning fast precision shifting
- 800 Series OCLV Carbon is the lightest laminate we’ve ever made
- The Aeolus RSL 37 wheels are designed for climbing, and were developed alongside Emonda
- Make it yours: it's fully customizable through Project One

Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:

Shifting Performance
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.

Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.

Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
