Roll faster and smoother with a reduced risk of punctures.

With UST Road Tubeless, no tube means no friction. So you experience less rolling resistance and higher speeds.
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.

Lighter, wider rims for quick, comfortable handling.

17 mm internal rim width for increased air volume.
ISM 4D superlight rim.
Double butted steel spokes.

Engineered durability lets you ride more miles without any worries.

Spoke and rim interface are secured with Fore drilling.
Sealed cartridge bearings designed to last many miles.

The Ksyrium Elite road wheel has been a benchmark for reliability, light weight and versatility for more than a decade.

This updated version makes it easier than ever to experience the benefits of riding tubeless. Integrated with our Yksion Pro UST Tubeless tires, the system makes installation, removal and maintenance simple and hassle-free. Eliminating the tube reduces friction in the system, which means less rolling resistance and higher speeds. You can also lower your tire pressure, which gives you a smoother, more comfortable ride plus added control on rough roads. And you’ll enjoy a reduced risk of punctures, so you can ride with confidence and push yourself farther.
The rims are engineered with our patented Fore Drilling to form a stronger connection between the spokes and the rim. Isopulse lacing improves stability and boosts lateral stiffness while sprinting or climbing. Our exclusive patented ISM 4D process strategically removes excess material from the rim while maintaining it around the spokes, where tension is applied.
The wheel is available in three color options: full black; gray on black; black with red highlights.

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.

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.

FTS-L

FTS-L

Force Transfer System Light
Reinforcement of key transmission components: the contact area between the pawl and the hub body is reinforced by 2 stainless steel inserts, which allows the use of a 100% aluminum hub body.

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.

On typical UK roads and doing the odd bunny-hop, clatter up kerbs and ploughing into several potholes I can report, these wheels are as bombproof as the previous model, with no truing required throughout testing. Stiffness is good too, with no noticeable flex or brake rub noted when sprinting or climbing.
