Speed Concept

Speed Concept is a lot of things, but above all, it’s fast. It's our most aerodynamic bike, which makes it an ideal triathlon bike and a great choice for TT enthusiasts who know every second matters. Plus, it's an exceptional value: adjustability, integration, customisation options, carbon aero wheels and an 11-speed drivetrain – all in a super aero bike built for flat-out speed.

It's right for you if...

You're out to win and you're looking for the aero advantage other triathlon bikes simply can't provide. You understand fit is a crucial part of going fast and you want a bike that's infinitely customisable to your perfect aero position.

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 brake set, 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.
