When you’re gunning for the KOM on the toughest mountain climbs, nothing gives you more of a boost than a light and snappy carbon wheelset. This newcomer in the Cosmic family takes over the venerable Ksyrium Pro Carbon SL Disc. It features a reengineered carbon rim that’s the lightest in its category. Its 32mm airfoil shape slices through wind, and because the rim is made specifically for disc brakes, you’ll have more confidence and control on the descents.

The rim is crafted with a new laminate and our exclusive Fore Carbon technology that leaves the upper rim bridge intact and reinforces the rim only where needed. This saves 40g per wheel. The spokes attach to the rim without any need to drill the upper rim bed, so no rim tape is required. That means more weight savings (30g per wheel) and less hassle. The new shape of the rim bed makes it easier than ever to mount and remove tires, and you get super low rolling resistance with our UST Tubeless setup. No tube means no friction, and more air volume means a smoother, faster ride. It also uses our patented elliptical spokes to save another 5 watts and make you faster.
Our new Infinity hub platform optimizes spoke lacing for efficient power transfer through highly controlled spoke tension. Our Instant Drive 360 freewheel, coupled with our automatic bearing preload adjustment (QRM Auto), provides fast engagement, high stiffness and added durability. It's available for Shimano and SRAM XD-Road and can convert to Campagnolo with an optional driver body. It's compatible with 12x100 axle up front, 12x142 rear, and you can convert to Quick Release with the supplied adapters. For Center Lock disc rotors only.
These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in our European carbon factory.

UST tubeless technology

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.

QRM Auto bearing preload technology

QRM Auto bearing preload technology

Qualité de Roulements Mavic Auto
Our latest innovation. 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.

Fore Carbon tapeless tubeless technology

Stiffer and stronger
Instead of drilling the rim to attach the spokes and nipples, a threaded metallic insert is wrapped inside the carbon layups of the lower rim bridge to enable the spoke nipples to be directly screwed in it.
As a result, the upper rim bridge is left undrilled and doesn't require the use of a rim tape to be sealed.
