Mavic Cosmic SL 32 Disc

Mavic Cosmic SL 32 Disc


This carbon road wheel climbs and corners faster with a lighter weight 32mm rim featuring UST Road Tubeless technology and disc-brake-specific engineering.

With quick acceleration and a lightweight, efficient feel on the climbs, this newcomer in the Cosmic family takes over the venerable Ksyrium Pro Carbon UST. Carbon rims and disc-brake control give you an added advantage in the mountains and hills. It features the same rim as our pro-level SLR 32 model, which means superlight full carbon construction for easier climbing and instant acceleration.

Fast climbing and snappy acceleration

  • Reduced inertia of a lighter weight rim delivers instant acceleration
  • NACA inspired rim shape (32mm deep) minimises aerodynamic drag
  • Flat double-butted spokes save weight and improve responsiveness

Laterally stiff for improved power transfer

  • Infinity hub platform optimizes lacing and spoke tension to improve wheel stability
  • Strong hub axle and ID360 freewheel technology for instant acceleration

Improved UST Road delivering speed, comfort and control

  • No tubes means less friction, improved efficiency and grip with reduced risk of punctures
  • Rim bed shape makes it easier to mount and change tyres

Weight: 1499g


The 21mm internal rim width is optimised for 28mm tyres to deliver a smooth, efficient ride on a variety of road surfaces. The refined spokes help make this rim 80g lighter than its predecessor. The Infinity hub platform adds stiffness, so the wheels feel quick and responsive out of every corner.

The Road Tubeless system lets you run lower tyre pressure for improved rolling efficiency, a smoother ride quality, and a reduced risk of flats. The rim bed shape makes it easier than ever to mount and remove tyres. If your typical rides include tough climbs, technical cornering and descents, the Cosmic SL 32 Disc is a fast, easy way to supercharge your road bike.

These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in their European carbon factory.


Instant Drive 360 technology

Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.

UST tubeless technology

Traction and control. The UST concept improves traction, control and comfort whilst reducing inertia and flats

Infinity Hub Design

An ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear.

QRM Auto bearing preload technology

Qualite de Roulements Mavic Auto. Cartridge bearings are double sealed with e3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
