About this bike
Trek is well aware that every second counts, so their Speed Concept 7.5 is all about denying the clock. Optimum aerodynamics and serious speed come from the full-carbon frame that uses unique Kammtail shapes that cheat the wind even when it's coming from the side. Other aero tricks include hidden brakes, cables and a computer sensor that's built into the chainstay. Even the wheel quick releases hide from the wind, while the Bontrager tires do their part optimizing airflow. Beyond just aero, it's also a rocket when hammering on the pedals, providing excellent pedaling efficiency for maximum speed whether you go short or long. And the 7.5 boasts a proven Shimano Ultegra/Dura-Ace parts group for pro-level shifting and light, aero Bontrager wheels for free speed.
