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.
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 fetaure 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.
