With a fully integrated cockpit and Trek's KVF (Kammtail Virtual Foil) tube modelling; the Trek Speed Concept 7.5 Triathlon Bike 2017 is designed to provide you with a dominating aerodynamic advantage. On top of this wind-cheating frameset comes the smooth shifting of SRAM's Force 22 11-speed groupset and the lasting comfort of Bontrager's RXL Hilo Saddle.

Trek Speed Concept 7.5 Triathlon Bike 2017

Beat the wind and dominate your competition with the Trek Speed Concept Trek Speed Concept 7.5 Triathlon Bike 2017. Complete with several upgrades over the Speed Concept 7.0 model, this bike utilises years of wind tunnel and real-world testing to provide you with an aerodynamic advantage out on the road.

The incredibly fast frame is formed with a Kammtail Virtual Foil (KVF) design, which is the most aerodynamic tube shape ever designed for a bicycle. Trek have made KVF even more aerodynamic by reducing the frontal area of the bike and reducing drag at all yaw angles.

In addition to the KVF modelled frame, Trek also integrate the Speed Fin underneath the bottom bracket. This fin works with the integrated rear brake to enhance rear wheel braking and stability while also acting as a rear-wheel fairing for greater aerodynamic performance.

SRAM's Force 22 groupset provides a benchmark in exemplary mechanical gearing with smooth and reliable shifting while the Quarq semi-compact crankset provides a gear ratio that will allow you to power over hilly courses while still maintaining a high-speed on the flat.

Bontrager's Integrated Speed Limit brakes not only enhance the aerodynamic performance of the bike, they also combine with the Bontrager Tubeless Ready wheelset to provide confidence-inspiring braking performance in both the wet and the dry.

One area that is often overlooked with triathlon and time trial bikes is comfort, but not with the Trek Speed Concept 7.5 Triathlon Bike 2017. Bontrager's RXL Hilo saddle with hollow titanium rails alleviates pressure build up and numbness while also supporting your sit bones through the entire circumference of the pedal stroke.
