Miles ahead of other bikes in its class and out on the road, too, Trek's Speed Concept 7.5 is all about optimum aerodynamics and serious speed. Its carbon frame uses unique Kammtail shapes that cheat the wind even when it's coming from the side and are stiff for awesome pedaling efficiency and compliant for comfort. Other aero tricks include the hidden cables, rear brake and computer sensor 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 fine Shimano Ultegra/Dura-Ace parts group for pro-level braking and shifting and fine Bontrager wheels for more free speed.
