Mavic Cosmic SL 40 Wheelset

This wheelset has it all, aerodynamics, lightweight and performance for all terrain conditions. Refined spokes make this wheelset 80g lighter than its predecessor, the Cosmic Pro Carbon UST. Combined with the all-new Infinity hub platform, which makes them feel quick and responsive out of every corner, they are stiffer and more efficient. 

Mavic Cosmic SL 40 Wheelset rim is engineered with a NACA rim profile that’s 40mm deep and 26mm wide, designed specifically for all-rounder performance on flat or hilly terrain. The new 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. 

Mavic Cosmic SL 40 Wheelset is engineered specifically for rim brakes, with Mavic’s 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.These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in their European carbon factory.
