Read more500 Series OCLV achieves a superb balance of light weight, strength, and stiffness that's perfectly suited to the sophisticated frame technologies that distinguish Trek frames.
Learn moreWe went beyond the wind tunnel to make the world's fastest bike even faster. We factored in real-world conditions, tested on actual courses, and again left the competition behind.
Learn moreTri bikes are not known to be mechanic friendly. But Speed Concept changes that. It’s faster to build, easier to adjust, simpler to pack for race travel. You’re welcome.
We tested every shape possible, and found this 6:1 ratio is fastest where it matters most. This fork slices the wind from 2.5-12.5 degrees of yaw angle without stalling for unparalleled aerodynamic performance in real-world wind conditions.
Bar is integrated into the frame for the sleekest, lowest-drag profile.
Bontrager integrated Speed Storage products are so well fitted to the Speed Concept frame that you and your bike are actually more aerodynamic with them than without.
Our exclusive Kammtail Virtual Foil (KVF) is the most aerodynamic tube shape ever designed for a bicycle. And now it's even faster, with less frontal area and reduced drag at all yaw angles.
Kammtail virtual foilDon't settle for anyone else's bike. Create your very own with Project One, Trek's custom bike program.
