The frameset, wheels, cockpit and other parts are engineered, developed and tested together to perform as a system. The all-new OverDrive Aero steerer tube technology is combined with a Contact SL AeroLight stem and Contact SL handlebar to incorporate internal cable routing that integrates the top cap, cables and spacers in a more aerodynamic, user-friendly setup.

Featuring a greater stiffness-to-weight ratio than the previous generation, along with new aero tube shaping and a lighter overall weight, this uncompromising race bike delivers explosive acceleration and unyielding pedaling stiffness. The result is race-winning performance in the moments that count.

All tube shapes are engineered and developed using Computational Fluid Dynamics (CFD) modeling and wind-tunnel testing. From the truncated ellipse shape of frameset tubing to a new cockpit design and component integration, it all adds up to a more streamlined profile that improves overall aero performance compared to the previous generation.
