Aerodynamics, instant acceleration and handling improved by UST Tubeless
: it's all in our carbon road wheel! On the program, Road Tubeless technology and ever more lightness
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 40
lightness and responsiveness on hill climbs and acceleration.
The rim features a 40mm high and 26mm wide NACA profile, specially designed to support all types of performance on flat and hilly terrain without fail. 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. Combined with our brand new Infinity hub platform, which guarantees responsiveness in any situation, they are stiffer and more efficient.
The Cosmic SL 40
is designed specifically for rim brakes. The proven iTgMax process includes patented laser treatment of the brake band. It helps reduce stopping distance in both dry and wet weather. The layered design and heat treatment process helps make the strongest and most durable of all carbon rims designed for rim brakes. The + product:
Accelerate and climb more efficiently, reach 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.
- Tightened flat spokes lighten the wheel and improve responsiveness
Versatility and performance whatever the conditions
- The reduced drag, low inertia and high lateral stiffness of the Cosmic Pro Carbon Disc TDF make it a fast and efficient wheel on all types of terrain, from plains to uneven in the mountains.
- ITgMAX brake band is the best of all carbon rims in terms of braking efficiency and reliability
The optimized UST Road system allows for more speed, more comfort and better handling, all with a
