Aerodynamics, efficient acceleration and handling improved by UST Tubeless : the choice is quick, everything is in this road wheel specially designed for disc brakes! On the program, Road Tubeless technology and ever more lightness.

This versatile carbon road wheel is perfect for riders looking for the perfect balance of weight, aerodynamics and efficiency. New spokes and hubs give the Cosmic SL 45 Disc lightness and responsiveness on hills and acceleration.
The rim features a 45mm high and 26mm wide NACA profile, specially designed for flawless support for all types of performance on flat and hilly terrain. With the new rim top deck profile, fitting tubeless or inner tube tires has never been so easy.

Who says UST Tubeless says no inner tube, so no friction, and a larger volume of air promises a smoother ride. The result: increased speed with greatly reduced rolling resistance. The improved spokes allow this wheelset to save 80g over its predecessor, the Cosmic Pro Carbon UST Disc.
Combined with our brand new Infinity hub platform, which guarantees responsiveness in any situation, these wheels are stiffer and more efficient.
a Cosmic SL 45 Disc is specially designed for disc brakes, with an optimized number of spokes and shelving.

These wheels are designed, manufactured and patented by Mavic, in Annecy, and entirely handmade on our European site.
