The Mavic Cosmic Pro Carbon Ust Disc Front Wheel has long been a leader in maximizing performance and value, especially in the realm of aero speed. New innovations have made it more of an all-rounder, and this UST tubeless disc-brake version delivers incredible all-around performance at a light weight (1650g) and a price that can't be beat. 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.
