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 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 and reliability, especially on long, steep descents. 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.
