This versatile carbon road wheel is ideal for cyclists seeking the perfect balance between weight, aerodynamics and efficiency. New spokes and hubs give the Cosmic SL 45 Disc a light and lively feel when climbing and accelerating.
The rim is designed with a 45 mm deep and 28 mm wide NACA profile, specifically designed for allrounder performance on flat or hilly terrain. The new rim bottom shape makes it easier than ever to fit tubeless and tubular tyres. UST Tubeless means no tubes, so no friction, and more air volume means a smoother ride. The result is a faster ride with very low rolling resistance. The improved spokes make this wheel 80g lighter than its predecessor, the Cosmic Pro Carbon UST Disc. Combined with our brand new Infinity hub platform, which makes the wheels fast and responsive in every turn, they are stiffer and more efficient.
The Cosmic SL 45 Disc is designed specifically for disc brakes, with an optimised number of spokes and lacing. They are only offered in a Center Lock version and are compatible with 12mm through axles and can be converted to quick release with the included adapters. They are available for Shimano cassettes and can be converted to SRAM XD-R or Campagnolo with an optional guide body.
These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in our European carbon factory.
Accelerate and climb faster, maintain higher speeds
The NACA-inspired 45mm rim shape minimises aerodynamic drag for greater speed. The reduced inertia of the lightweight rim guarantees immediate acceleration. Double-cut flat spokes reduce weight and improve responsiveness.
Versatile performance for all road riding conditions
Minimum aerodynamic drag, low inertia and high lateral stiffness make it fast and efficient on all types of terrain, from flat to mountain climbs. Disc brake-specific construction for better control and compatibility with 12 mm through axles
Improved UST Road offers greater speed, comfort and control in an easy-to-use tubeless system
The absence of tubes means less friction, greater efficiency and grip, and a reduced risk of punctures. New rim bottom shape facilitates tyre fitting and replacement
Infinity hubs
Efficient power transfer through optimised non-contact spoke lacing (no noise under load) and tension distribution. Front and rear spoke lengths are identical. Easy maintenance thanks to tool-free solution.
QRM Auto bearing adjustment technology
Quality Mavic Auto bearings. These cartridge bearings are naturally double sealed, with C3 internal clearance. The system automatically adjusts to ensure perfect rotation without play in the long term.
Instant Drive 360 freewheel system
The new Instant Drive 360 freewheel system is ultra-light and efficient. A non-contacting, oversized rubber seal minimises friction and a wide choice of adapters makes it compatible with a wide range of frames and axles.
Tubeless UST technology
Traction and control. Universal Tubeless Standard. Ready-to-ride tubeless system. The UST system improves traction, control and comfort while reducing inertia and the risk of punctures.
