QRM Auto bearing preload technology

QRM Auto bearing preload technology

Qualité de Roulements Mavic Auto
Our latest innovation. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.

UST tubeless technology

UST tubeless technology

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.

iTgMAX carbon clincher technology for rim brake

iTgMAX carbon clincher technology for rim brake

Integral Glass Transition Temperature
iTgMAX consists in an inner rim bed finished with multiple layers of seamless carbon fiber to achieve a unique one-piece rim contour without cutting any fibers. The brake track is then finished with a laser machining to ensure the best braking efficiency

Isopulse lacing design

Isopulse lacing design

Optimum energy transfer
The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges.
