UST Road Tubeless lets you ride with lower tire pressure for smoother ride and a reduced risk of punctures
Our patented UST system offers a perfect union between tire and wheel, so installation, removal and maintenance are easy

Climb, accelerate and sprint faster

17mm internal rim width increases air volume
ISM 4D superlight rim
Double-butted steel spokes keep the weight down, for a fast and comfortable ride

Powerful, reliable disc brakes for more confidence and control

24 spokes front and rear for optimized brake torque distribution
Front hub convertible from 12mm or 15mm thru-axle to quick release
Rear hub convertible from 12x142 thru-axle to quick release
6-Bolt or Center Lock brake compatible

A favorite for everyday road training and racing, this versatile wheel system produces a lightweight, dynamic ride quality that now has the added benefits of our UST Road Tubeless technology. This patented system provides seamless integration between the wheel and our new Yksion Pro UST tubeless tires that makes installation, removal and maintenance easier than ever. And you get all the benefits of tubeless, including less rolling resistance and a smoother, more controlled ride quality. Without tubes, you can run lower tire pressure without risking pinch flats, and the sealant helps prevent punctures. The rims are engineered using our ISM 4D technology and now feature a wider design (19mm internal/23mm external). ISM stands for Inter Spoke Milling, a unique process that trims the thickness of the rim wall between the spokes to create a rim that’s lighter but still very durable. To reinforce the front wheel for disc brakes, we increased the spoke count to 24. The hub is compatible with a 12mm thru-axle, 15mm thru-axle or quick release. The rear wheel uses 24 straight-pull spokes laced to our lightweight, fast engagement Instant Drive 360 hub mechanism. Delivered in 12x142, it can be also converted to regular quick release. It’s compatible with Shimano or SRAM cassettes and can be converted to Campagnolo or SRAM XD-R.

Ksyrium Elite UST Disc is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from True Tubeless for a Road Tubeless Newbie Received these a couple days before the Haute Route Rockies in June. These are solid, bombproof wheels that are light, responsive and a workhorse of high-quality. I was able to set up the UST quickly and easily with a floor pump in just a few minutes. My experience w/tubeless tech is limited to my MTB and typically asking for help like a true roadie. At HRR, rode all week around 60psi Yksion Pro 28mm (7 days, 875km and 16,000m). I only had 2 flats via one full-speed pinchflat. Placed tubes in on the spot and continued.

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.

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.

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.

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.

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.

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

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.
