When the road tilts towards the sky, Trek's 16.3-pound Emonda SL 6 reacts to every pedal stoke, its OCLV carbon frame and BB90 bottom bracket launching you forward effortlessly. Then, as you get into the business of descending, the E2 head tube keeps the front end nice and stiff, and Bontrager tubeless wheels keep you carving the curves. Along the flats, a full Ultegra 11-speed drivetrain with compact cranks combines with internal cable routing to propel you to faster speeds. And on every road, the Ride-Tuned seatmast is not only lighter, it's more compliant than a traditional seatpost while the full Bonty cockpit is more than eager to add some additional miles.
