BUILT TO GO FASTER. WHETHER YOU’RE CLIMBING, CORNERING OR LAUNCHING AN ATTACK, THIS ALL-NEW COMPOSITE ROAD RACER IS MADE FOR THAT MOMENT. LIGHTWEIGHT, EFFICIENT, AND INTEGRATED FOR SPEED, IT’S ENGINEERED TO GIVE YOU A COMPETITIVE EDGE IN EVERY SITUATION.
KEY PERFORMANCE FACTORS
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.
