Details of the Mavic Cosmic SL 45 Disc Carbon

The rim bed shape makes it easier than ever to fit tubeless and tube-type tires.

Riding UST Tubeless means no tube, so no friction and more air volume means a smoother ride.

The result is a faster ride with super low rolling resistance.

Refined spokes make this wheelset 80g lighter than its predecessor, the Cosmic Pro Carbon UST.

Combined with the Infinity hub platform, which makes them feel quick and responsive out of every corner, they are stiffer and more efficient.

The Cosmic SL 45 Disc is engineered specifically for disc brakes and comes with an optimized spoke count and lacing.
