Road UST WTS by the inventor of Tubeless

Lowest rolling efficiency
Best pinch flat protection
Highest safety with easiest mounting

Light and nimble alloy rim

Multipatented ISM4D brings rim weight and inertia to a level that is out of reach of our competitor, for unsurpassed climbing and descending abilities
Superlight Zicral spokes

Strong and stiff

Fore drilling makes for a solid rim/spoke connection while ensuring high rim stiffness and perfectly sealed rim bed for simple tubeless compatibility
Zicral spokes add stiffness while reducing weight

Equally adept on fast, rolling roads or mountain terrain, the Ksyrium Pro UST delivers comfort and performance for a variety of riding conditions. Key updates include a UST tubeless compatible rim. When combined with our new 25mm Yksion Pro UST tubeless tires, the result is an 15% increase in rolling efficiency at equal tyre pressure. Or 5% rolling resistance improvement with 1bar /15PSI lower pressure to get extra comfort and grip.

Other major updates include redesigned lighter hub shells, the implementation of our fast engagement Instant Drive 360 hub and new automatic adjustment of the bearing preload for long terms smoothness with no lay.
Still laced with our proprietary Zicral alloy spokes that are stiffer, stronger and lighter than traditional stainless steel spokes. The Isopulse lacing pattern (radial lacing on the drive side) allows a more balanced spoke tension for a stiffer, more stable wheel.
Fore drilling creates the strongest possible connection between rim and spokes, increasing stiffness by about 20%, and makes tubeless super easy to use, without the need for a rim tape.
Each part of the rim is precisely machined using just the right amount of material to provide stiffness and strength, while maintaining weight at only 400g. All in all, the total wheel weight is down to an impressive 1420g.

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.

QRM Auto

QRM Auto

Qualité de Roulements Mavic Auto
Our latest innovation. Those cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to guarantee a perfect spin with no play on the long run.

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

UB Control

UB Control

Usiné Brut Control
The braking surfaces are precisely CNC machined.

Instant Drive 360

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.

11 Storm

11 Storm

Exclusive rubber compound that offers the best blend of rolling efficiency and grip

Maxtal

Maxtal

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

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.

SUP

SUP

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

Zicral

Zicral

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

UST

UST

Traction and control
Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort whilst reducing inertia and flats.

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.
