Mavic Cosmic SLR 45 Disc Racing Wheels Disc Brake

by Mavic

This brand new carbon wheelset is a great choice for road cyclists who want to be fast and efficient in all riding and racing conditions. Not only does the 45mm aero rim cut through the wind with minimal drag, it is also the lightest in its class.

A new rim laminate paired with our unique Fore Carbon technology leaves the top bridge of the rim intact and strengthens the rim only where needed, saving 40g per rim. The spokes are fixed to the rim without having to drill the upper groove of the rim, without flaps. This results in greater weight savings (30 g) and fewer complications in fitting or repairing tubeless tires. The new rim groove shape also makes it easier than ever to fit and remove. The UST Tubeless configuration means no air chamber, no friction and more air volume for a smoother ride. The result is faster pedaling with ultra-low rolling resistance. Finally, our patented elliptical beams save another 5 watts.

Our new Infinity hubs optimize spoke lacing for efficient power transfer through highly controlled spoke tension. The Instant Drive 360 ​​freewheel combined with automatic bearing preload adjustment (QRM Auto) provides quick engagement, high stiffness and increased strength. It is available for Shimano and SRAM XD-Road drivetrains and can be adapted to the Campagnolo system with an optional drivetrain. It is compatible with 12x100 front and rear and 12x142 axles, and can be converted to the quick release system thanks to the adapters provided. 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.
