With fast acceleration and a lightweight, efficient feel on climbs, this new addition to the Cosmic family takes the place of the venerable Ksyrium Pro Carbon UST. Carbon rims and disc brake control offer an added advantage in the mountains and hills. It features the same rim as our pro-level SLR 32 model, which means a super-light full carbon structure for easier climbing and instant acceleration.
The 21mm inner rim width is optimised for 28mm tyres to offer a smooth and efficient ride on a variety of road surfaces. New, improved spokes contribute to making this rim 80 g lighter than its predecessor. The new Infinity hub platform adds rigidity, so the wheels are fast and responsive in every turn.
Our Road Tubeless system reduces tyre pressure for greater rolling efficiency, smoother ride quality and reduced risk of punctures. The new rim bottom shape makes tyre mounting and demounting easier than ever. If your typical rides involve tough climbs, technical turns and descents, the Cosmic SL 32 Discs are a quick and easy way to upgrade your road bike.
These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in our European carbon factory.
Fast climbing and snappy acceleration
The reduced inertia of a lighter rim offers immediate acceleration The NACA-inspired rim shape (32 mm deep) minimises aerodynamic drag Double-curved flat spokes save weight and improve responsiveness
Lateral rigidity for improved power transfer
The new Infinity hub shape optimises lacing and spoke tension to improve wheel stability. Robust hub axle and ID360 freewheel technology for instant acceleration
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 makes tyre fitting and changing easier
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.
