What Our Gearhead® Experts Are Saying:
"If you’re chasing that sweet spot between aero efficiency and climbing responsiveness, the Cosmic SL 45 Disc nails it. The 45mm rim depth gives you real aero gains without getting twitchy in crosswinds, and Mavic’s Infinity hub setup makes every watt count. They’re light, stiff, and ready for everything from race days to long training blocks."
Engineered for aerodynamic speed and everyday rideability, the Mavic Cosmic SL 45 Disc 23mm Wheelset brings wind-tunnel-tested performance to your road setup. The 45mm deep carbon rims slice through the air while maintaining confident handling across varying conditions, making them a true all-rounder for racers and endurance riders alike.
Mavic’s refined Infinity hub platform maximizes power transfer with instant engagement, while flat aero spokes further reduce drag to save watts on every turn of the pedals. With a 23mm internal width optimized for modern, wider road tires, the Cosmic SL 45 balances responsiveness, comfort, and rolling efficiency whether you’re sprinting for the line or spinning over mountain passes.
