Trusted Mavic technologies and design, all packaged in a lightweight, durable wheelset with a stunning finish make this a smart upgrade for any road rider
This lightweight aluminum wheelset is a no-brainer for anybody looking to make an easy upgrade from OEM wheels. The Ksyrium S can significantly boost any bike's performance and is an easy entry point to Mavic quality that doesn't take any shortcuts.
The Ksyrium S is 60g lighter than the former Ksyrium UST while also being wider, stronger, and laterally stiffer. Stiffness is optimized using Fore technology. The upper bridge remains undrilled, optimizing strength and rigidity, and it doesn’t require the use of rim tape, which saves another 30g per wheel. The rim bed’s new shape makes it easier than ever to mount and remove tires, and our UST Tubeless technology improves rolling resistance and grip while reducing the risk of punctures. Those rims are made in France, in our aluminum rim factory.
Our new Infinity hub platform optimizes stiffness and power transfer with highly controlled spoke tension, while an Instant Drive 360 freewheel coupled with our automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability. The Ksyrium S doesn’t just ride fast, it looks fast too. Matte-painted hubs, invisible rim welding, and deep black spokes give this wheelset a premium look that stands out from the crowd.
It's available for Shimano cassettes and can convert to Campagnolo or XD-Road with optional driver bodies.

Lightweight and durable for everyday performance
Rim weighs only 430g No rim tape is needed, saving 60g over a traditional wheel Flat, lightweight spokes and ID360 freewheel technology
Laterally stiff and vertically compliant for a more dynamic ride
Fore technology keeps the rim upper bridge solid to make the 19mm wide rim stiffer New Infinity hub platform: stiff axle, durable bearings, and new hub design
Improved UST Road delivers more speed, comfort, and control in an easy-to-use tubeless system
No tubes mean less friction, better efficiency, and grip, and reduced risk of punctures new rim bed shape makes it easier to mount and change tires. Fore drilling technology doesn't require the use of rim tape.

Maxtal
Light and strong Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.
Fore tapeless tubeless technology
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 freewheel technology
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.
UST tubeless technology
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 lacing design
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.
SUP welding technology
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.
