Mavic Cosmic SLR 45 Disc


This all-new carbon wheelset is a great choice for road riders aiming to be fast and efficient in all types of riding and racing situations. Not only does the 45mm airfoil rim slice through the wind with minimal drag, but it’s also amongst the lightest in its category. This season, the external carbon layer features our new UD2 construction for a distinctive look and an even lighter rim laminate, saving another 15g per rims.

A new rim laminate coupled with our exclusive Fore Carbon technology leaves the upper rim bridge intact and reinforces the rim only where needed, saving 40g per rim. 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) and less hassle when it comes to set up or repair tubeless tyres. The new shape of the rim bed makes it easier than ever to mount and remove tires. UST Tubeless setup means no tube, so no friction, and more air volume means a smoother ride. The result is a faster ride with super low rolling resistance. At last, our patented elliptical spokes save another 5 watts.

Our new Infinity hub platform optimizes the spoke lacing for efficient power transfer through highly controlled spoke tension. The Instant Drive 360 freewheel with automatic bearing preload adjustment (QRM Auto) provides fast engagement, high stiffness and added durability. It’s available for Shimano and SRAM XD-Road driver bodies and can convert to Campagnolo with an optional driver body. It’s compatible with a 12×100 axle up front, and 12×142 rear, and converts to Quick Release with 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.


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 control. Ready to ride tubeless system. 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.
