Mavic Cosmic SL 45 Disc 2024 Wheels

This versatile carbon road wheel is perfect for cyclists looking for the perfect balance of weight, aerodynamics and efficiency. New spokes and hubs give the Mavic Cosmic SL 45 Disc lightness and responsiveness on hills and acceleration.

The rim features a 45mm high and 26mm wide NACA profile, specially designed for seamless support for all types of performance on flat and undulating terrain. With the new rim upper deck profile, mounting tubeless or inner tube tires has never been so easy. Who says UST Tubeless means no inner tube, therefore no friction, and a greater volume of air promises smoother riding. Result: increased speed, with greatly reduced rolling resistance. Improved spokes allow this wheelset to gain 80g over its predecessor, the Cosmic Pro Carbon UST Disc. Combined with our all-new Infinity hub platform, which ensures they're responsive in any situation, these wheels are stiffer and more efficient.

The Cosmic SL 45 Disc is specially designed for disc brakes, with an optimized spoke count and lacing. Available for Center Lock system only, they are compatible with a 12mm thru axle and convertible to quick release using the adapters provided. They can be equipped with Shimano and SRAM XD-R cassettes, and are convertible to Campagnolo using an optional freehub body.
These wheels are designed, manufactured and patented by Mavic , in Annecy, and entirely handmade on our European site.

Highlights of Mavic Cosmic SL 45 disc:

  • Accelerate and climb with more efficiency, reach higher speeds: Reduced drag and increased speed thanks to 45mm rims inspired by NACA profiles. The lightness of the rim reduces inertia and allows immediate acceleration. The narrowed flat spokes lighten the wheel and improve its responsiveness
  • Versatility and performance whatever the conditions: The reduced drag, low inertia and high lateral rigidity of the Cosmic SL 45 Disc make it a fast and efficient wheel on all types of terrain, from plains to mountain slopes Special brake design disc, which allows better handling and compatibility with 12 mm thru axles
  • The optimized UST Road system allows for more speed, more comfort and better handling, all with an easy-to-use tubeless system: No inner tube means less friction, more efficiency and grip, and better protection against punctures New rim upper deck profile makes mounting and changing tires easier
