Technologies

Infinity Hub
Equipped with the all-new Infinity Hub that harnesses a trinity of hallmarks that enhance power transfer, durability, and compatibility. Easily serviceable without the need for specialized tools, the Instant Drive 360 freewheel technology ensures quick engagement along with high rigidity and durability and offers automatic bearing preload adjustment (QRM Auto). Designed for compatibility and ease of use, the Infinity Hub can be converted to all major freewheel drive options and axle dimensions.

UST Tubeless Technology
Traction, control and lightweight. The UST concept improves traction, control and comfort while reducing inertia and flats. Tubeless constructions are lighter, reduce the rolling resistance and provides more comfort.

QRM (Qualité de Roulements Mavic)
Qualité de Roulements Mavic. Mavic only uses high quality sealed cartridge bearings. On QRM wheels, they feature double sealing (2RS or LLU) together with tight C3 internal clearance.
