**additional information**
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 thatâs 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 laminate and mavic's 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 the 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.
The infinity hub platform optimises spoke lacing for efficient power transfer through highly controlled spoke tension. The instant drive 360 freewheel, coupled with automatic bearing preload adjustment (qrm auto), provides fast engagement, high stiffness and added durability. 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.
**technologies**
**fore carbon tapeless tubeless technology**
stiffer and stronger. A fully sealed upper rim bridge eliminates the need for rim tape. The spokes are directly screwed in the insert. A threaded metallic insert is wrapped inside the carbon layups of the lower rim bridge.
**instant drive 360 technology**
super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
**ust tubeless technology**
traction and control. The ust concept improves traction, control and comfort whilst reducing inertia and flats
**infinity hub design**
an ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear.
**qrm auto bearing preload technology**
qualite de roulements mavic auto. Cartridge bearings are double sealed with e3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
