Mavic Cosmic SL 40 700c QR Rim Brake Carbon Fibre Rear Wheel (Shimano HG/SRAM)

If You Wanna Go Fast.
Mavic's redesigned 40mm rim and easier to use Road Tubeless technology, saves 40gm per rim. You'll find you can accelerate and climb faster and hold higher speeds (what's not to like). Mavic's Cosmic SL 40 Disc all-new carbon wheel 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 40mm airfoil rim slice through the wind with minimal drag, it's also the lightest in its category.

Medium Profile Rim
When a racer is looking for perfect versatility, Mavic's Fast & Light Wheel-Tyre System line is the perfect answer. Mavic's Fast & Light WTS feature the best blend of lightweight, high stiffness and great aerodynamics to deliver the highest possible efficiency.

Wheel Efficiencies
Mavic's new Infinity hub platform optimises 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.

Mavic Tubeless
A new rim laminate saves 40g per rim, and the new shape of the rim bed also makes it easier than ever to mount and remove tyres. 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. Finally, Mavic's patented elliptical spokes save another 5 watts.

Handmade in Europe
These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100% handmade in Mavic's European carbon factory.
