Meticulously developed for best-in-class aero road performance, this razor-sharp composite road racer was born to sprint, chase and make your attack.

Key Performance Factors

Integrated aerodynamics

AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR/SL Aero cockpit produce the best overall aero performance.

Total control

Integrated disc brakes deliver smooth, powerful control and modulation for added confidence in all conditions. Flat mounts and thru-axles boost stiffness and improve overall handling, and an integrated WheelSystem with a 65mm rear rim and shallower 42mm front rim optimizes aerodynamics and control.

Unrivaled efficiency

Advanced-grade composite frameset features high-performance materials and proprietary manufacturing processes for optimized stiffness and the lowest weight in its category.

  • Weight
    The 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.
