Mavic Crossmax Carbon SLR 29 Boost Rear 2025

Mavic Crossmax Carbon SLR is designed for aggressive cross-country performance, this lightweight 29” wheel features a full-carbon hookless rim to boost quickness, efficiency and control on modern technical XC terrain. If high-intensity cross-country is your game, this is your wheel. Engineered around a 25mm wide rim, the Crossmax Carbon SL R 29 is made for modern XC riding and racing. The full carbon rim delivers lightning-fast acceleration and helps you float up technical climbs, and it has just enough vertical compliance to help you nail every line with precision and control. The external carbon layer features our new UD² construction for a distinctive look and added durability. The 25mm inner width is designed to pair well with any modern XC tire. The rim is laced with 24 straight-pull, double-butted spokes to help achieve a perfect balance between lateral stiffness and vertical compliance. We created a lighter weight hub infinity that, combined with the rim stiffness and strategic spoke lacing, maximizes your pedaling forces for superior power transfer.
