Features
Integrated handlebar
Bar is integrated into the frame for the sleekest, lowest-drag profile.
KVF tube shape
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 foil
Ultra-clean front end
Move around to the front of Speed Concept and an amazing thing happens: it all but disappears. Fully integrated handlebar with hidden shift and brake cables presents 30% less surface to the wind. It's the lightest, cleanest, most aero front end ever.
Fast build, easy adjustment
Tri 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.
500 Series OCLV
500 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.

Integrated Speed Storage
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.
Beyond the wind tunnel
We 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.

Full-foil fork
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.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
