SYSTEM OPTIMIZATION
The frameset, wheels, cockpit and other parts were engineered, developed and tested together to perform as a system. The all-new Contact AeroLight stem allows for 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 pedaling stiffness. The result is race-winning performance in the moments that count.
INTEGRATED AERODYNAMICS
All tube shapes were 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.
MADE FASTER
Newly integrated components including the Contact AeroLight stem create a sleeker, more aero profile. The Variant seatpost adds just enough compliance for a balanced, race-tuned feel on the road, while generous tire clearance (up to 33mm) and compliant wheels keep you rolling with speed on smooth or bumpy roads.
ADVANCED COMPOSITE
High-performance grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
TRUNCATED ELLIPSE TUBING
Strategically engineered airfoil sections in the frame and fork, developed through CFD and wind-tunnel testing, improve aerodynamic efficiency, reducing wind drag at a wide range of yaw angles compared to traditional teardrop shaped tubes.
INTERNAL CABLE ROUTING
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and easier adjustability.
COMPOSITE FORK
Advanced-grade composite fork features a symmetric design and aero shaping, along with disc-brake integration and increased clearance for tires up to 33mm. The design makes it lighter, stiffer and more aerodynamic.
AERODYNAMIC HANDLEBAR AND STEM
Lightweight handlebar and stem feature aero shaping including flat handlebar tops with raised edges to help riders maintain a stable aero position. Internal cable routing further improves aerodynamics while maintaining ease of setup and adjustment.
VARIANT SEATPOST
This proprietary seatpost design offers the perfect balance of light weight, aerodynamic performance and compliance, along with easy saddle installation and adjustment.
MEGADRIVE
An oversized down tube and top tube provide superior front end lateral and torsional stiffness. The precisely engineered, rectangular shaped down tube yields unprecedented steering precision and pedaling performance.
POWERCORE
The oversized bottom bracket area features a fully integrated 86mm wide design. Symmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
DISC-BRAKE INTEGRATION
The frame and fork are engineered with flat-mount disc-brake technology for powerful, consistent braking performance in all conditions.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. 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
