UST Tubeless Ready

UST Tubeless Ready

Traction, control and lightweight
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.

Maxtal

Maxtal

Light and strong
Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.

QRM+

QRM+

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.

X-mix

X-mix

The right dual compound mix
Faster rolling, more durability and confident cornering is what is required from a high performance tyre.
Softer side knobs and a firmer but still grippy rolling tread serve many riding situation. Each tyre receives the right mix for its dedicated program.

Zicral

Zicral

Light, stiff and strong
A specific aluminum alloy that provides spokes with higher stiffness-to-weight ratio while being stronger.

ITS-4

ITS-4

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.

Isopulse

Isopulse

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.

ISM 4D

ISM 4D

Inter Spoke Milling 4 Dimensions
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

Fore

Fore

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.
