Mavic Cosmic SLR 45 Disc Front Wheel Road Bike Disc Front Wheel | Bike-Discount

With its lighter, 45 mm high rims and the new UD² finish, the Mavic Cosmic SLR 45 carbon wheel is the fastest, stiffest and lightest all-rounder for road bikes with disc brakes.

The lightest rim in its category: the Cosmic SLR 45 Disc from Mavic

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. 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 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.

Infinity Hub
Equipped with the all-new Infinity Hub that harnesses a trinity of hallmarks that enhance power transfer, durability, and compatibility. Easily serviceable without the need for specialized tools, the Instant Drive 360 freewheel technology ensures quick engagement along with high rigidity and durability and offers automatic bearing preload adjustment (QRM Auto). Designed for compatibility and ease of use, the Infinity Hub can be converted to all major freewheel drive options and axle dimensions.

UST Tubeless Technology
Traction, control and lightweight. The UST concept improves traction, control and comfort while reducing inertia and flats. Tubeless constructions are lighter, reduce the rolling resistance and provides more comfort.

QRM (Qualité de Roulements Mavic)
Qualité de Roulements Mavic. Mavic only uses high quality sealed cartridge bearings. On QRM wheels, they feature double sealing (2RS or LLU) together with tight C3 internal clearance.
