About this bike
Some wins are measured in seconds. On Trek's Speed Concept 9.9 you'll measure your improvements in minutes! The full OCLV carbon frame delivers unrivaled aerodynamics with Trek's Kammtail tubes that cheat the wind even at serious real-world wind angles. It's also brilliantly light and stiff for outstanding acceleration and cornering. Notice anything missing? The cables, brakes, electronics, and even the skewers are hidden, out of the wind. There's even integrated storage that makes the frame more aero. Plus, the shifting is telepathic with Dura-Ace Di2 and the Aeolus wheels increase this unfair advantage on any course. Faster, lighter, better. Just like you!
