Details of the Mavic Cosmic SL 40 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 40 is engineered specifically for rim brakes. The proven iTgMax technology features a patented laser treatment of the brake track that shortens stopping distance in both dry and wet conditions, while a special lay-up and heat treatment process makes it the strongest and most durable of all carbon rims for rim brakes.
