An exclusive Mavic patented concept, ISM 4D significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance; the right mix to make the most of any ride. The smooth profile also helps reducing aerodynamic drag.
Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than conventional 6106 alloy.
Using 4 pawls working 2 by 2, Instant Transfer System 4 provides a more dynamic ride, thanks to a very fast engagement. Its versatility makes it compatible with all kinds of frame retention system.
The UST concept improves traction, control and comfort while reducing inertia and flats. The Tubeless Ready construction results in a lighter tyre for improved performance.
Mavic only uses high quality sealed cartridge bearings. On QRM wheels, they feature double sealing (2RS or LLU) together with tight C3 internal clearance.
