The rim is designed with a 45mm deep and 26mm wide NACA rim profile, specifically designed for all-round performance on flat or rough terrain. The new shape of the rim base makes it even easier to mount tubeless or chamber tires. UST Tubeless means tubeless, so there is no friction, and more air volume means a smoother ride. The result is a faster ride with very low rolling resistance. Optimized spokes make this wheelset 80g lighter than its predecessor, the Cosmic Pro Carbon UST Disc. Combined with our new Infinity hub platform, which provides a greater feeling of speed and response in every curve, they are stiffer and more efficient. This Cosmic SL 45 Disc has been specifically designed for disc brakes, optimising the spoke count and lacing tension. They are only available in Center Lock.
