The S2 pioneered carbon aero road bicycles.

  • S2 2015 black

The original S2 design set standards that are now copied across the aero road segment. To redefine this model we had to imagine the perfect S2 experience—the last sprint on your Saturday morning group ride, or a long, solo straightaway at the edge of town—and make every part of that ride better. The new S2 offers an all-new frame and fork, with increased stiffness and refined aerodynamics. This is a bike that delivers maximum performance at a value-conscious price.

Wherever your personal finish line is, we’ll get you there faster.

    Smooth shifting that is easy to set up is no accident. Designing shifting requires a detailed approach. Small details have a huge impact.
