MAIN FEATURES Accelerate and climb with more efficiency, maintain higher speeds Reduced drag and increased speed thanks to 40mm rims inspired by NACA profiles.The lightness of the rim reduces inertia and allows immediate acceleration.Butted flat spokes lighten the wheel and improve its responsiveness. Versatility and performance in all conditions The reduced drag, low inertia and high lateral stiffness of the Cosmic SL 40 make it a fast and efficient wheel on all types of terrain, from plains to mountaindrops The iTgMAX braking track is the best of all the rims in carbon in terms of braking efficiency and reliability The optimized UST Road system allows for more speed, more comfort and better handling, all with an easy-to-use tubeless system Who says no inner tube means less friction, more efficiency and grip, and better protection against puncturesThe new profile of the upper bridge of the rim makes mounting and changing tires easier
