Designed for aggressive cross-country performance, the lightweight Mavic Crossmax SL R 29″ wheel with carbon Hookless rim excites with top speed, efficiency and control on technical XC courses.
Laterally stiff and vertically compliant feel: the Crossmax SL R from Mavic
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. Mavic created a lighter weight hub infinity that, combined with the rim stiffness and strategic spoke lacing, maximizes your pedaling forces for superior power transfer. The Instant Drive 360 freewheel with a double ratchet system provides fast engagement so you can sprint and accelerate out of corners faster. The rear hub is compatible with Shimano HG9, Micro Spline and SRAM XD driver bodies. The Crossmax SL R is available with 6-bolt or center lock brake rotors in 29” only and is compatible with a 15×110 front axle and 12×148 rear. The wheel is delivered with valves, replacement spokes and accessories.
