Mavic Cosmic Pro Carbon UST Road Wheelset


The pinnacle of carbon clincher performance, the Mavic Cosmic Pro Carbon UST combines lightweight aero design with Mavic’s UST road tubeless technology. The result is an incredibly capable all-rounder with super-low rolling resistance; a smoother, more comfortable ride quality; and the added security of a reduced risk of punctures. Plus, it’s the most user-friendly tubeless system when it comes to installation, removal and maintenance. 

As a pioneer in tubeless technology with their proven UST system, Mavic gives you the confidence that comes with a deep history and expertise. The rim design of the cosmic pro carbon UST features a 19mm inner width that’s ideal for 25mm tires while the aerodynamic NACA profile reduces wind drag and improves crosswind stability. 

The rim is produced with layers of continuous carbon fiber to achieve a unique one-piece contour straight out of the mold. This technique, which Mavic call ITgmax, offers superior heat management, allowing the rim to withstand temperatures up to 200° c their unique molding process and laser machining achieves a consistent braking track with nearly zero surface variations. This results in the shortest braking distances in both dry and wet conditions, with superior consistency. 

The hubs are laced with their patented aero spokes. The system is completed with Yksion pro UST tyres, which provide a simple, hassle-free tubeless road setup with high rolling efficiency and maximum grip in all weather.
