Mavic Cosmic SL 45 Disc Wheels

Less drag, more watts thanks to the 45 mm rim profile and flat spokes developed by our aerodynamics experts and tested in the vento tunnel, with INFINITY hubs, the power transfer is ultra-efficient and the wheel is even more responsive. The lightweight 23mm rim and spoke pattern make the Cosmic SL 45 Disc the most versatile Mavic road wheel ever designed.

Technologies

Instant Drive 360 freewheel system

The new Instant Drive 360 freewheel system is ultra-light and efficient. A non-contact oversized rubber seal minimises friction and a wide choice of adapters makes it compatible with a wide range of frames and axles.

UST Tubeless Technology

Traction and control. Universal Standard for Tubeless. Tubeless system ready to ride. The UST system improves traction, control and comfort, reducing inertia and the risk of punctures.

Infinity Hubs

Efficient power transfer thanks to optimized non-contact spoke lacing (no noise under load) and voltage distribution. The length of the front and rear spokes is identical. Easy maintenance thanks to the tool-free solution.

QRM Auto Bearing Automatic Adjustment Technology

Quality Mavic Car Bearings. These cartridge bearings are of course double sealed, with C3 internal clearance. The system adjusts automatically to ensure perfect rotation without backlash in the long term.
