Aero in Everything
The SL8 redefines aerodynamic performance with its innovative Speed Sniffer nose cone and refined frame shaping, reducing drag where it matters most.
Minimum Weight, Maximum Speed
At just 685g for the frame, it’s significantly lighter than the previous generation while maintaining elite stiffness and aero performance.

Increased compliance and stiffness-to-weight improvements deliver a bike that climbs efficiently, descends confidently, and stays comfortable over long distances.

Built for every rider, the SL8 focuses on performance data rather than outdated gender-based design.
