Superlight, ultra-efficient and rides like a dream. This well-rounded race bike blends industry-leading composite frame engineering with fully integrated components to help you climb, corner and descend with astonishing speed and sublime road handling.

Key Performance Factors

SYSTEM OPTIMISATION

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.

WINNING EFFICIENCY

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 pedalling stiffness. The result is race-winning performance in the moments that count.

INTEGRATED AERODYNAMICS

All tube shapes are engineered and developed using Computational Fluid Dynamics (CFD) modelling 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.

Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
