With its widened 23mm UD carbon rim, the Mavic Cosmic SL 45 is the most versatile of Mavic's carbon wheels, offering improved comfort and performance. 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 are all provided with this disc-brake specific wheel, featuring easier-to-use road tubeless technology and lighter weight.
The rim is engineered with a NACA rim profile that's 45mm deep and 23mm 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 their European carbon factory.
Key Technologies:
- Instant Drive 360 Technology: Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
- UST Tubeless Technology: Traction control. Ready to ride tubeless system. The UST concept improves traction, control, and comfort whilst reducing inertia and flats.
- Infinity Hub Design: An ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear.
- QRM Auto Bearing Preload Technology: Qualite de Roulements Mavic Auto. Cartridge bearings are double sealed with E3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
