Key Benefits

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.

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.
