The pinnacle of carbon clincher performance, the all-new Cosmic Pro Carbon SL UST combines lightweight aero design with Mavic's all-new 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 the proven UST system, Mavic gives you the confidence that comes with their 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 Mavic call iTgMax, offers superior heat management, allowing the rim to withstand temperatures up to 200° C. Mavic's 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 Mavic's lightweight, fast-engaging Instant Drive 360 freewheel system, laced with their patented aero spokes. And the system is completed with Mavic's Yksion Pro UST tires, which provide a simple, hassle-free tubeless road setup with high rolling efficiency and maximum grip in all weather. The Cosmic Pro Carbon SL UST works with Shimano or SRAM cassettes. It’s convertible to Campagnolo or SRAM XD with optional driver bodies.
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
