Technologies

Instant Drive 360 freewheel system
The new Instant Drive 360 freewheel system is ultra-light and efficient. A non-contact oversized rubber seal minimises friction and a wide choice of adapters makes it compatible with a wide range of frames and axles.

UST tubeless technology
Traction and control. Universal Tubeless Standard. Ready-to-ride tubeless system. UST improves traction, control and comfort, reducing inertia and the risk of punctures.

Infinity Hubs
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the front and rear spokes is identical. Easy maintenance thanks to tool-free solution.

QRM Auto bearing adjustment technology
Quality Mavic Auto bearings. These cartridge bearings are naturally double sealed, with C3 internal clearance. The system automatically adjusts to ensure long-term perfect rotation without play.
