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.


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 energy transmission
Instant Transfer System 4: Using 4 pawls working 2 by 2, the system provides a more dynamic ride, thanks to a very fast engagement. Its versatility makes it compatible with all kinds of frame retention system.
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.
Qualité de Roulements Mavic +
Our most demanding level. Those cartridge bearings are of course double sealed with C3 internal clearance, and toped with a micro-adjustability system.


Spoke Retention System
The hub shell slots special machining makes sure that the spoke head is imprisoned and will not pop out of the hub. The spoke still can travel in the slot, in order to let the wheel absorb some of the terrain obstacles.
Light and strong
Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.


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.
