Lightweight, aero and tubeless UST carbon rim is built for speed.

40mm NACA-inspired rim shape minimizes drag for added speed. Reduced inertia of the lightweight rim delivers instant acceleration. Mavic Road Tubeless UST improves rolling efficiency.

Experience versatile performance for all road riding conditions.

Ideal balance of minimal drag, low inertia and high lateral stiffness makes it fast and efficient on all types terrain, from the flats to mountain climbs.

Highest performance without compromise.

Best braking efficiency of carbon clinchers thanks to iTgMAX.
Best-in-class tire grip thanks to UST and 11Storm compound.
High flat protection thanks to UST and easy on-the-road tire repair.

The Cosmic Pro Carbon has traditionally been favored primarily for fast, flat races, but recent improvements have boosted this wheel's versatility. Now it delivers incredible all-rounder performance at a lighter weight (1490g) and a price that can't be beat. Engineered with Mavic UST technology, the Cosmic Pro Carbon UST offers all the benefits of tubeless, including less rolling resistance, a smoother ride quality and a reduced risk of flats. The rims are made using our iTgMax process, which not only minimizes weight, but also improves braking performance. The 40mm deep rims are NACA compliant for low drag and excellent crosswind stability, and their lighter weight results in reduced inertia for explosive acceleration and climbing efficiency. The Cosmic Pro Carbon UST is completed with 25mm Yksion Pro UST tires for maximum rolling efficiency, grip and a smooth, comfortable ride.

UST Tubeless Ready

UST Tubeless Ready

Traction, control and lightweight
The UST concept improves traction, control and comfort while reducing inertia and flats.
The 'tubeless ready' construction results in a lighter tyre for improved performance.

iTgMAX

iTgMAX

Integral Glass Transition Temperature
iTgMAX consists in an inner rim bed finished with multiple layers of seamless carbon fiber to achieve a unique one-piece rim contour without cutting any fibers. The brake track is then finished with a laser machining to ensure the best braking efficiency

QRM
