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. Made faster this versatile road racer combines race winning stiffness to weight with aerodynamic tube shaping and system integration. From the road smoothing variant seatpost to the composite wheelsystem every piece is made to perform better as a system. The new overdrive aero steerer tube technology is combined with a contact sl aerolight stem and contact sl handlebar to incorporate new internal cable routing for easy setup and adjustment while integrated disc brakes and generous clearance for tyres up to 33mm make it adaptable to all road conditions. 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.
