CROSSMAX SL S 29
Cross-country racing puts a multitude of demands on a wheelset. You want one that helps you climb with speed and efficiency, descend with greater control, and track through the rough stuff with smooth confidence. The Crossmax SL S is a lightweight alloy wheel that does it all.

Engineered with a specific rim profile that combines a 25mm internal width and our patented ISM4D technology, this wheelset can boost the performance of your bike with a price that’s accessible compared to carbon wheel options. The ISM4D process machines the rim in the areas with less stress to reduce weight without compromising strength. The rim also features our Black Shield technology, which protects against scratches and dents so you can charge hard through rock gardens and rough singletrack.

The rims are made with our patented Fore technology with a fully sealed upper rim bridge that eliminates the need for rim tape. This saves 30 grams per wheel, not to mention the hassles associated with tape when setting up tubeless tires. New Infinity hub is lighter and feature a new spoke lacing which increases stiffness for better power transfer, and the Instant Drive 360 freewheel with a double ratchet provides fast engagement. The rear hub is compatible with Shimano HG9, Micro Spline and SRAM XD driver bodies. The Crossmax SL S is available with 6-bolt or center lock brake rotors in 29” only. It’s compatible with a 15x110 front axle and 12x148 rear, and comes with valves, replacement spokes and accessories.

Main features

Best in its class alloy XC wheelset

ISM4D rim machining reduces weight to close the gap to carbon rims without compromising strength. Lighter weight rims result in super low inertia and instant acceleration.

Increased traction and durability

25mm wide hookless rim profile optimized for lower tire pressures, resulting in improved grip in all conditions. Optimized for modern XC tubeless tires from 2.1 to 2.30". Black Shield treatment protects rims against impacts and scratches.

Most user-friendly tubeless system

Fore technology fully sealed rim with no rim tape makes it easy to mount and change tubeless tires. Leaving the upper rim bridge intact boosts the stiffness and durability of the rim.

Key technology

LightnessMaxtal aluminum alloy
Light and strong. Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.
LightnessISM 4D light rim technology
Inter Spoke Milling 4 Dimensions is an exclusive Mavic patented concept. The ISM 4D significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance ; the right mix to make the most of any ride. The smooth profile also helps reducing aerodynamic drag.
Efficiency RigidityFore tapeless tubeless technology
Stiffer and stronger. Instead of being drilled, the lower rim bridge is pushed up on the inside, then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intact.
Efficiency RigidityInstant Drive 360 freewheel technology
The new Instant Drive 360 freewheel system is super light and efficient. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
Efficiency RigidityUST tubeless technology
Traction and control. Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats.
Safety ReliabilitySUP welding technology
Soudé Usiné Process, stronger and smoother joint. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
Safety ReliabilityBlack Shield treatment (protects your rim against impacts and scratches)
This treatment doubles the rim's lifespan against stone impacts and scratches. Super strong double coated treatment with a matt finish.
Safety ReliabilityInfinity hub design
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution.
Safety ReliabilityQRM Auto bearing preload technology
Qualité de Roulements Mavic Auto. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
