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.

Aero efficiency, quick acceleration and the improved ride quality of UST Tubeless. You get it all with this disc-brake specific wheel featuring easier to use Road Tubeless technology and lighter weight.

Faster acceleration and climbs

• Flat double butted spokes saves weight and improves responsiveness
• Reduced inertia of the lightweight rim delivers instant acceleration.

Versatile performance for all road riding conditions

• Minimal drag, low inertia and high lateral stiffness makes it fast and efficient on all types of terrain, from the flats to mountain climbs
• Disc-brake-specific build for improved control and compatibility with 12mm thru axles

Improved UST Road delivering speed, comfort and control

• No tubes means less friction, improved efficiency and grip with reduced risk of punctures
• Rim bed shape makes it easier to mount and change tyres

ADDITIONAL INFORMATION

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 rim bed shape makes it easier than ever to fit tubeless and tube-type tyres. 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 the 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 Centre 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.
