MAVIC CROSSMAX ULTIMATE 29" Rear Wheel 12x148mm Boost
Unable to load pickup availability
Description
The MAVIC CROSSMAX ULTIMATE 29" rear wheel is designed for competitive cross-country riding and prioritises lightweight performance, responsiveness and precision. At just 1080 g per pair, it features a fully optimised design to reduce rotating mass and promote sharp acceleration, particularly on climbs and when accelerating again.
The Adaptive Layup carbon rim combines different T700, T1000 and 3K fibres to achieve a balance of low weight, lateral stiffness and vibration absorption. Its 30 mm internal width and hooked Tubeless Ready design are suited to modern XC tyres, with a recommended width of 2.3 to 2.4 inches.
The carbon spokes combined with titanium nipples help reduce overall weight while ensuring an excellent stiffness-to-weight ratio. Each wheel uses 20 two-cross spokes, a configuration designed to optimise power transfer, steering precision and line-holding in technical sections.
The ID360 Ultralight 40-tooth freehub system provides rapid engagement and direct power transfer. The ultra-lightweight aluminium hubs are fitted with Mavic Ceramic bearings, while the 15x110 mm Boost front axles and 12x148 mm rear axles ensure compatibility with the relevant MTB standards.
Hand-built and then checked in Mavic's Chavanod laboratory, the Crossmax Ultimate wheels undergo rigorous validation. They accept tubeless, tubeless-ready or inner-tube tyres and are rated ASTM Level 3, with a maximum load of 135 kg.

Key features
Adaptive Layup technology optimises each layer of carbon fibre to achieve the ideal balance of lightness, lateral stiffness and vibration absorption. The result is a rim offering remarkable steering precision, exceptional responsiveness and race-proven efficiency.
Carbon spokes combined with titanium nipples significantly reduce rotating mass while providing exceptional stiffness. Their specific 20-spoke 2-cross lacing pattern delivers the ideal level of flex to maintain total control right up to the final lap, even in the most technical sections.
Mavic Ceramic bearings: Low friction + absolute precision = consistent performance, ride after ride.
Complete assembly at the Mavic laboratory: each wheel follows a rigorous, controlled Mavic assembly protocol (tensioning, balancing, dynamic validation); nothing is left to chance.
