For all-around cross-country performance, including faster climbing and descending, this premium 29" alloy wheelset delivers stiffness, durability and the easiest tubeless system available today.

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.

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
Optimised for modern XC tubeless tyres 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 tyres. Leaving the upper rim bridge intact boosts the stiffness and durability of the rim
Weight: 1615g

ADDITIONAL INFORMATION

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 Mavic's 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. The Infinity hub is lighter and features a 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 centre 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.

Technologies

Maxtal aluminium alloy

Light and strong. Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than the conventional 6106 alloy.

ISM Light rim technology

Inter Spoke milling is an exclusive Mavic patented concept. ISM involves the machining of the lower bridge of the rim between each spoke hole to create a light and rigid rim without reducing durability

Fore Carbon tapeless tubeless technology

Stiffer and stronger. A fully sealed upper rim bridge eliminates the need for rim tape. The spokes are directly screwed in the insert. A threaded metallic insert is wrapped inside the carbon layups of the lower rim bridge.

Instant Drive 360 technology

Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.

UST Tubeless technology

Traction control. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats

SUP Welding technology

Soude Usine Process, stronger and smoother joint. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.

Black shield treatment

This treatment doubles the rim's lifespan against stone impacts and scratches. Super strong durable coated treatment with a matt finish

Infinity Hub Design

An ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear.

QRM Auto bearing preload technology

Qualite de Roulements Mavic Auto. Cartridge bearings are double sealed with e3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
