Mavic Cosmic S 42 Disc Front 2025

Welcome to a new dimension in cycling. The Mavic Cosmic S 42 Disc wheel, with its ultralight all-carbon rim, delivers instant acceleration and improved control.

Thanks to a 21mm internal width, this wheel maximizes tire volume, increasing confidence, improving efficiency and optimizing cornering performance.

A profile height of 42mm and wind-tunnel-tested flat spokes maximize the Cosmic S 42 Disc’s aerodynamics and give it lateral stability at high speeds. Cyclists looking for versatility on undulating or mountain roads will find what they're looking for. Low weight guarantees excellent capabilities on the toughest slopes, so you can tackle the Alpe d'Huez like it’s a hill. Mavic’s UST Tubeless Ready technology simplifies tire installation, offering improved comfort and efficiency.

High-quality spokes, durable bearings and Mavic ID360 freewheel technology guarantee exceptional strength and longevity. Hand-assembled in Europe, the Cosmic S 42 Disc is the result of Mavic’s extensive experience in manufacturing high-quality wheels.
