MEET MAVIC'S NEW COSMIC SL 40 RIM BRAKE WHEELSET

The Mavic Cosmic SL 40 is an extremely versatile carbon road wheelset ideal for rim brake riders seeking to balance weight, aerodynamics and efficiency. New spokes and hubs give the Cosmic SL 40 a light and lively feel for climbing and accelerating.

The 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 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 an all-new Infinity hub platform, which makes them feel quick and responsive out of every corner, they are stiffer and more efficient than their forebears.

The Cosmic SL 40 is engineered specifically for rim brakes. 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. They are available for Shimano cassettes, and convert to Campagnolo and SRAM XD-R with optional driver bodies.
