Wheels - Hubs

XC, redefined. Equally ready on the start line or the trailhead, this wheelset meets the descending and climbing needs of modern XC, and then some. Where it thrives: In competition, challenging trails What it's built for: Precision, control, efficiency Highlights: - Carbon fiber construction, 25mm internal width, tubeless compatible - DT Swiss Aerolite spokes / DT Swiss 240 hub internals - 28h straight pull hubs / Weight: 1470g (pair)

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-arounder performance at a price that can't be beaten. 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. Lightweight, aero and efficient - 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. 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. - Best braking efficiency of carbon clinchers thanks to iTgMAX 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
