Welcome to Trek's boundary-pushing, high-performance, ultra-light race machine, the Emonda SLR 9. With a frame weight of just 690 grams, the Emonda tickles the scales at mere 13.45 pounds! And that's only part of the story. Light is nothing if the ride is anything shy of brilliant. Not to worry, Trek does carbon like no one else, so it's stiff where you demand it, and smooth where you need it. The geometry was tweaked with direct pro racer feedback so it's crisp, tight and aggressive. Telepathic shifting is yours with Dura-Ace Di2, and you cross the finish line with time to spare on 35mm-deep, carbon Bontrager Aeolus wheels. Two fits are available, H1 for aggressive, flexible racers, while the H2 fit delivers a slightly more upright ride. One ride and you will believe.
