Mavic Cosmic SL 32 C21 carbon bike wheels 2026

The Mavic Cosmic SL 32 C21 are back with a new version featuring a more modern design and just as high a level of performance. Designed to go fast on mountain passes, these wheels are more laterally rigid for improved power transfer. UST Road technology offers greater speed, comfort and control thanks to an easier-to-use tubeless system. Inspired by NACA profiles following wind tunnel testing, the rim shape is designed to minimise aerodynamic drag. The flat, double-butted spokes help reduce weight and improve responsiveness. With a 32 mm profile and an internal width of 21 mm, the Mavic Cosmic SL 32 C21 wheels are lightweight and specially developed to offer you the best possible experience on climbs. These wheels are responsive thanks to the Infinity hubs, which ensure ultra-efficient power transfer. Lightweight and efficient, the Instant Drive 360 freehub system minimises friction, whilst the QRM bearings offer excellent smoothness. Technical specifications: - Discipline: road (mountain)
