NEW 2025
Designed to go faster. Whether you're climbing, taking a turn or launching an attack, this all-new composite road bike is made for that moment. Lightweight, efficient and built for speed, it's designed to give you a competitive advantage in every situation.
SYSTEM OPTIMIZATION
The frame, wheels, cockpit and other components have been designed, developed and tested together to function as a complete system. The full Contact AeroLight stem allows for internal cable routing, integrating the top cap, cables and spacers into a more aero and user-friendly configuration.
WINNING EFFICIENCY
Featuring a higher stiffness-to-weight ratio than the previous generation, as well as new aero tube profiling and a lighter overall weight, this no-compromise race bike delivers explosive acceleration and unwavering power transfer. The result is a winning racing performance for crucial moments.
INTEGRATED AERODYNAMISM
All tube shapes were designed and developed using computational fluid dynamics (CFD) modeling and wind tunnel testing. From the truncated ellipse profile of the frame tubes to a new cockpit design and component integration, everything contributes to creating a more aerodynamic profile that improves overall performance compared to the previous generation.
