DESCRIPTION
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.
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.
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.

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
