Cosmic Pro Carbon wheels have long been a leader in maximizing performance, especially when it comes to maximizing aerodynamics and lightweight properties. New innovations have made it more of an all-arounder, and this UST tubeless disc-brake version delivers incredible all-around performance at a low weight (1650g) and a price that can't be beaten. Engineered with Mavic UST technology, the Cosmic Pro Carbon UST Disc offers all the benefits of tubeless, including less rolling resistance, a smoother ride quality, and a reduced risk of flats.

The 45mm 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 wheels are engineered specifically for disc brakes, with an optimized spoke count and lacing.
The Cosmic Pro Carbon UST is completed with 25mm Yksion Pro UST tires for maximum rolling efficiency, grip, and a smooth, comfortable ride.

Lightweight, aero, and efficient
- 45mm NACA inspired rim shape minimizes drag for added speed.
- Reduced inertia of the lightweight rim delivers instant acceleration.
- Mavic Road UST improves rolling efficiency.

Versatile performance for all road riding conditions
- Minimal drag, low inertia, and high lateral stiffness make it fast and efficient on all types of terrain, from the flats to mountain climbs.

Better tire grip and control with reduced risk of flats
- Best-in-class tire grip thanks to UST and 11Storm compound
- High flat protection thanks to UST and easy on-the-road tire repair
- Optimized spoke count, lacing, and hub compatibility for use with disc brakes

Tubeless technology

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 beads. UST rims should be paired with UST-specific tires for best results.
