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.
KVF tube shape
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.
Ultra-clean front end
Incredibly svelte! Fully integrated handlebar with hidden gear shift and brake cables presents 30% less surface to the wind. The lightest, cleanest, most aero front end ever.
Speed Concept is the first bike with front and rear brakes built directly into the fuselage. This innovative setup results in less drag and cleaner lines.
The fastest fit
Nothing fits like Speed Concept, thanks to the best fit window in the industry. You'll feel the difference, from the bike leg through to the finish line.
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.
We tested every shape possible in the wind tunnel and on the course in pursuit of this no-holds-barred full-foil aero fork.
Speed Concept 9.9
