Speed Concept - Trek Bikes (INE)

Overview

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.

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.

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.

It's a triathlon superbike that's proven to be the fastest in the wind tunnel

Features

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.

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.

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.

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.

Kammtail Virtual Foil 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

Move around to the front of Speed Concept and an amazing thing happens: it all but disappears. Fully integrated handlebar with hidden gear shift and brake cables presents 30% less surface to the wind. It's the lightest, cleanest, most aero front end ever.
