Mavic has launched its new flagship cross-country mountain bike wheelset, the Crossmax Ultimate. Engineered for elite World Cup XC racing, the redesigned wheelset sheds 300 grams compared to its predecessor, reaching an impressive total weight of just 1,080 grams per pair (500g front / 580g rear).

Key Technical Innovations

According to technical analysis by Escape Collective, the 300-gram weight reduction is distributed evenly across three main areas:

Adaptive Layup Carbon Rims (−100g): Features a 25mm profile and a modern 30mm internal width (36mm external) hookless design optimized for 2.3″–2.4″ tires.

The raw T700/T1000/3K composite construction requires no post-mold machining, saving 50g per rim while enhancing compliance.

Carbon Spokes & Titanium Nipples (−100g): Uses 20 straight-pull carbon spokes per wheel in a 2-cross pattern, secured by titanium nipples to significantly reduce rotational inertia.

UltraLight Ceramic Hubs (−100g): Weighing just 105g (front) and 180g (rear), the hubs feature Mavic ceramic bearings and a fast-engaging 40-tooth ID360 Light ratchet system.
