Best in its class alloy XC rim

ISM4D rim machining reduces weight to close the gap to carbon rims without compromising strength.

Increased traction and control 

25mm wide hookless rim profile optimized for lower tire pressures, resulting in improved grip in all conditions. Optimized for modern XC tubeless tires

Accelerate quicker

Lighter weight rims result in super low inertia and instant acceleration.

XC 1025 is the latest version of Mavic “XC” rims, and as such is the most advanced evolution.
Offering both lightweight and a wider 25mm profile, this welded rim features ISM 4D technology (Inter Spoke Milling), which strategically removes material from the rim where it’s not needed but keeps it around the spokes, where tension is applied. This technology makes the rim lighter, for faster accelerations, without compromising durability.
Optimized up to the limit of material potential, XC 1025 is probably the best Cross-Country alloy rim on the market.
Available in 28 and 32 holes, 29” only.

ISM 4D light rim technology

ISM 4D light rim technology

Inter Spoke Milling 4 Dimensions
An exclusive Mavic patented concept, 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

SUP welding technology
