The tech you get
Lightweight 500 Series OCLV Carbon frame, drag-reducing Kammtail Virtual Foil (KVF) tube shaping, Speed Concept full foil carbon fork, full Shimano Ultegra 11-speed drivetrain with Dura-Ace bar end shifters, Bontrager Speed Limit integrated brakeset, fully integrated handlebar and stem, Bontrager Hilo Comp triathlon-specific saddle for an aggressive and aero position, and aerodynamic Bontrager Aeolus Comp OCLV Carbon TLR wheels.
The final word
When you ride Speed Concept, you're gonna go fast. A lightweight carbon frame, aero tube shaping, carbon wheels, and an 11-speed Shimano Ultegra drivetrain mean speed and efficiency where it counts. Triathletes, time trialists, general speed demons—this one's for you.

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.
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.
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.
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 Trek retailer.
