ISM light rim technology
Inter Spoke Milling
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 the durability of the rim.

Key benefits
Best in its class alloy Trail wheelset
Super strong rim with ISM machining minimizes weight without compromising strength.
More confidence and control on rugged trails
30mm wide rim is optimized for lower tire pressure, giving you a smoother ride with more traction and control. Triangular rim shape absorbs heavy impacts so you're free to bomb the descents.
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 the durability of the rim.
You never know what the trail might throw at you: steep climbs and white-knuckle drops, hero dirt and chunky rocks. Whatever trail features and fun you find, the new Crossmax XL S is ready to roll. This best-in-class alloy 29” wheel features many of the proven technologies that have long made Mavic a leader in MTB wheel innovation.
The rims are engineered with our patented Fore technology, featuring a fully sealed upper bridge that eliminates the need for rim tape. That saves 30 grams per wheel and does away with the hassle of using tape to set up tubeless tires. We use ISM rim machining, which removes material in strategic areas of the rim to minimize weight without compromising strength. The rim has a 30mm internal width, optimized to squeeze the best performance out of any modern trail tire, and our Black Shield technology gives them distinctive finish that protects against scratches and abrasions.
We use 24 straight-pull spokes to further dial in the sweet spot between lateral stiffness and vertical compliance. The Infinity hubs feature a stiffer and lighter construction that is enhanced by the ultra-reliable ID360 double ratchet system for fast engagement. The wheelset is set up for 6-bolt or center lock disc mounts and is compatible with Shimano HG9, SRAM XD, and Micro Spline freewheel bodies. It’s available in 29” only and ships with UST tubeless valves, spare spokes and accessories.

Key technologies
UST 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.
Instant 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.
Fore 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.
QRM Auto bearing preload technology
Qualité de Roulements Mavic Auto
Our latest innovation. 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.
Black Shield treatment (protects your rim against impacts and scratches)
New MTB rim treatment. 2x superior lifetime against rock impacts and scratches
SUP welding technology
Stronger and smoother joint
Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
