This versatile carbon road wheel is ideal for riders seeking the perfect balance between weight, aerodynamics and efficiency. New spokes and hubs give the Cosmic SL 45 Disc a light and lively feel for climbing and accelerating.
The rim is engineered with a NACA rim profile that’s 45mm deep and 28mm 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. Refined spokes make this wheelset 80g lighter than its predecessor, the Cosmic Pro Carbon UST Disc. Combined with our all-new Infinity hub platform, which makes the wheels feel quick and responsive out of every corner, they are stiffer and more efficient.
This Cosmic SL 45 Disc is engineered specifically for disc brakes, with an optimized spoke count and lacing. They are offered in Center Lock only and are compatible with 12mm thru-axles and can convert to quick release with included adapters. They are available for Shimano cassettes and convert to SRAM XD-R or Campagnolo with an optional driver body.
These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in our European carbon factory.
