Trek 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, customization 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 customizable to your perfect aero position.
The tech you get Lightweight 500 Series OCLV Carbon frame, drag-reducing Kammtail Virtual Foil (KVF) tube shaping, full Shimano Ultegra 11-speed drivetrain with Dura-Ace bar end shifters, fully integrated handlebar and stem, Bontrager Hilo Comp triathlon-specific saddle for an aggressive and aero position, and aerodynamic Bontrager Aeolus 5 Comp 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.
