Mavic Crossmax S Carbon 29" Boost 6 bolts wheelset 2026

Carbon performance

The Crossmax S Carbon is the ideal wheel for XC and light trail riders who want to enjoy the performance of carbon with an excellent balance of dynamism, comfort, control and reliability. The Mavic carbon MTB wheel – Crossmax S Carbon – is designed for XC and light trail riders who want a high-performance, reliable and easy-to-use pair of wheels for frequent and long rides. Its carbon rim, designed with Mavic's expertise, optimises the orientation of the fibres according to the real constraints of the terrain: the result is a lively and precise wheel that remains forgiving to preserve comfort and control in technical sections. Tubeless compatibility allows you to lower the pressure to improve grip, comfort and control, while reducing the risk of punctures. Combined with the Mavic hub and a design built for durability, it offers efficient power transfer and simplified maintenance. Positioned between a competition-oriented wheel and an aluminium option, the Crossmax S Carbon is the ideal choice for switching to carbon without losing versatility.

Adaptive Layup
Carbon is lighter than alloy, but weight always add up. Using the right amount of fibers where the rim is less stressed to reduce rim weight with no compromise on reliability, this gives wheels that are livelier and more enjoyable while climbing. Up to 70g saved per rim.

ID360
Dual ratchets freewheel system. Choose between 24t for less drag or 40t for quicker engagement. New seal for worry free ride, but in case it's a tool-free serviceability.

Improved responsiveness
The reduced inertia of the rim combined with INFINITY hub technology means instant acceleration.
