Details of the Mavic Cosmic SL 45

Improved aerodynamics: less drag, more watts thanks to the 45mm rim profile and flat spokes developed by aero experts and tested in the wind tunnel.

The shape of the rim bed makes it easier than ever to fit tires. Riding UST Tubeless means no inner tube. The result is less friction and more air volume for a smoother and faster ride with super low rolling resistance. Combined with the Infinity hub platform, which gives a fast and responsive feel, they are stiffer and more efficient. The Cosmic SL 45 Disc was specially developed for disc brakes and has an optimized spoke count and lacing.
