MAVIC Cosmic SL 32 Carbon CL Disc Tubeless road rear wheel 9/12 x 135/142 mm

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 our pro-level SLR 32 model, which means superlight full carbon construction for easier climbing and instant acceleration. The 21mm internal rim width is optimized for 28mm tires to deliver a smooth, efficient ride on a variety of road surfaces. And new refined spokes help make this rim 80g lighter than its predecessor. Our new Infinity hub platform adds stiffness, so the wheels feel quick and responsive out of every corner. Our Road Tubeless system lets you run lower tire pressure for improved rolling efficiency, a smoother ride quality, and a reduced risk of flats. The new 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 our European carbon factory.
