Mavic Cosmic SL 32 Disc 29/28" (622 mm) Disc Brakes 12x142 Shimano HG Center Lock Rear Wheel Wheels

This carbon road wheel climbs and corners faster with a lighter weight 32 mm rim featuring UST Road Tubeless technology and disc-brake-specific engineering.

Fast climbing and snappy acceleration

• Reduced inertia of a lighter weight rim delivers instant acceleration NACA inspired rim shape (32 mm deep) minimizes aerodynamic drag Flat double-butted spokes save weight and improve responsiveness

Laterally stiff for improved power transfer

• Infinity hub plaform optimizes lacing and spoke tension to improve wheel stability Strong hub axle and ID360 freewheel technology for instant acceleration

Improved UST Road delivers more speed, comfort and control in an easy to use tubeless system

• No tubes means less friction, better efficiency and grip, a reduced risk of punctures
• The rim bed shape makes it easier to mount and change tires

With quick acceleration and a lightweight, efficient feel on the climbs, this newcomer in the Cosmic family takes over the venerable Ksyrium Pro Carbon UST. Carbon rims and disc-brake control gives you an added advantage in the mountains and hills. It features the same rim as pro-level SLR 32 model, which means superlight full carbon construction for easier climbing and instant acceleration.

• The 21 mm internal rim width is optimized for 28 mm tires to deliver a smooth, efficient ride on a variety of road surfaces. And refined spokes help make this rim 80 g lighter than its predecessor. Infinity hub platform adds stiffness, so the wheels feel quick and responsive out of every corner.
• Road Tubeless system lets you run lower tire pressure for improved rolling efficiency, a smoother ride quality, and a reduced risk of flats. The rim bed shape makes it easier than ever to mount and remove tires. If your typical rides include tough climbs, technical cornering and descents, the Cosmic SL 32 Disc is a fast, easy way to supercharge your road bike.
• These wheels are designed, engineered and patented by Mavic in Annecy, France, and are 100 % handmade in European carbon factory.
