KEY BENEFITS
Improved aerodynamics
Less drag, more watts thanks to its 45mm rim profile and flat spokes developed by our aero experts and wind tunnel tested.
Even more responsive
With INFINITY hubs, power transfer is ultra-efficient and the wheel is even more responsive.
Unrivalled versatility
The lightness of its 23mm rim and its spoking make the Cosmic SL 45 Disc the most versatile Mavic road wheel ever designed.
Infinity hub design
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution.
QRM Auto bearing preload technology
Qualité de Roulements Mavic Auto. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
Instant Drive 360 freewheel technology
The new Instant Drive 360 freewheel system is super light and efficient. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
UST tubeless technology
Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats.

The set weighs 1555 g. The figure is also listed as wheelset weight in the specifications.
It uses Center Lock only. This indicates precise compatibility with that disc mounting system.
Compatibility is 12x100 at the front and 12x142 at the rear. Adapters are available for some conversions, but they are not included.
The material is 100% unidirectional carbon fibre. This detail identifies the rim material in the technical sheet.
The intended use is ASTM category 2: road and tracks with jumps lower than 15 cm. It is therefore designed for road use and routes with small irregularities.
The wheel is 700, with ETRTO size 622x23TC and an internal width of 23 mm. These figures define the rim size and internal section.
