AtEscapa, we have the next set of wheels for your road bike. TheMavic Cosmic SL 45 CL Shimano HG-R Wheel Set, made of carbon, stands out for its versatility and road performance. With an aerodynamic 45 mm-deep rim, it offers the ideal balance between speed, stiffness, and comfort—perfect for cyclists seeking consistent performance on all types of terrain.
Efficiency and Quick Acceleration
With quick acceleration and a light, efficient feel on climbs, these wheels take the baton from the venerable Ksyrium Pro Carbon UST in the Cosmic family. If your typical rides include tough climbs, technical corners, and descents, the Cosmic SL Disc is a quick and easy way to supercharge your bike. These wheels were designed, manufactured, and patented by Mavic in Annecy, France, and are 100% hand-built at its European carbon factory.
The rim shape makes mounting tires easier than ever. Riding UST Tubeless means doing away with the inner tube. The result is less friction and more air volume for a smoother, faster ride with very low rolling resistance. Combined with the Infinity hub platform, which provides a fast, responsive feel, they’re stiffer and more efficient. The Cosmic SL 45 Disc was developed specifically for disc brakes and features an optimized number of spokes and spoke pattern.
Improved Aerodynamics
The 45 mm rim profile was developed by aerodynamics experts and tested in a wind tunnel to reduce drag. The flat, aerodynamic spokes minimize turbulence and ensure efficient power transfer at high speeds.
INFINITY Hub Design
INFINITY hubs optimize spoke tension and distribute forces evenly between both wheels. They operate quietly under load and require no tools for maintenance.
QRM Auto and Instant Drive 360
QRM Auto automatically adjusts bearing preload for smooth, long-lasting performance. The Instant Drive 360 freewheel provides immediate engagement and low friction for efficient acceleration.
