'13 Trek

Miles ahead of other bikes in its class, against the clock, and out on the road, Trek's Speed Concept 7.5 is all about optimum aerodynamics and serious speed. Its full-carbon frame uses unique Kammtail shapes that cheat the wind even when it's coming from the side and provide excellent pedaling efficiency for maximum efficiency whether you go short or long. Other aero tricks include hidden brakes, cables and a computer sensor that's built into the frame. Even the wheel quick releases hide from the wind, while the Bontrager tires do their part optimizing airflow past the aero wheels. This clock-beater boasts a proven Shimano Ultegra/Dura-Ace parts group for pro-level braking and shifting and light, aero Bontrager wheels for more free speed.
