The 2019 Mavic Cosmic Pro Carbon SL 25mm UST Clincher Wheelset is a versatile option, perfect for those looking to race and train on the same setup. Constructed from carbon fibre, the 40mm deep rims boast phenomenal aerodynamics, high stiffness and low weight, while the sealed bearings ensure four season durability. Featuring Mavic’s signature Yksion Pro Tyres, the Cosmics offer a confidence inspiring ride in any weather.
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 our proven UST system, Mavic gives you the confidence that comes with our history and expertise. The rim design of the Cosmic Pro Carbon SL UST features a 19mm inner width that’s ideal for 25mm tires.
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 we call iTgMax, offers superior heat management, allowing the rim to withstand temperatures up to 200° C. Our 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 feature our lightweight, fast-engaging Instant Drive 360 freewheel system, laced with our patented aero spokes. And the wheel-tire system comes with Yksion Pro UST tires that provide a simple, hassle-free tubeless road setup with high rolling efficiency and maximum grip in all weather.
