The most advanced evolution of Mavic "XM" rims
Offering both lightweight and a wider 30mm profile, the welded Mavic XM 1030 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, XM 1030 is probably the best Trail rim on the market.
ISM4D (Inter Spoke Milling 4D)
An exclusive Mavic patented concept, ISM 4D not only significantly reduces weight and reduces inertia without compromising durability, but also improves aerodynamics due to its new rim shape. More advantages: up to 50 grams lighter for faster climbing; the lowest inertia for instant acceleration and a smooth aerodynamic rim shape to reduce drag.
UST (Universal Standard for Tubeless)
Traction and control. The UST concept improves traction, control and comfort while reducing inertia and flats. Enables to ride at lower tire pressure. UST rim profile with specific humps to fix securely the tire beads. Compatible with all types of tires (UST, Tubeless Ready, clincher with tube).
SUP (Soudé Usiné Process)
A welded and milled rim joint which is extremely strong, eliminates shuddering when braking and offers superior wheel balance.
