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.


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


Instant Drive 360

The new Instant Drive 360 freewheel system is super light and fast to engage with only 9?. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.


Light. Stiff and strong.
A specific aluminium alloy that provides spokes with higher stiffness to weight ratios while being stronger.


Stiffer and stronger.
Instead of being drilled, thelower rim bridge is pushed up on the inside, then threaded to enable the soke nipples to be directly screwed in it, leaving the upper rim bridge intact.


Stronger and smoother.
Soude Usine Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.


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.


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.


High quality double sealed with C3 internal clearance, and toped with a micro-adjustability system.
