Welcome to the Mavic website

KSYRIUM S DISC
This lightweight aluminum wheelset is a no brainer for anybody looking to make an easy upgrade from OEM wheels. The Ksyrium S Disc 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 Disc is 40g lighter than the former Ksyrium UST Disc while also being 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 a 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 our Instant Drive 360 freewheel coupled with our automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability. The Ksyrium S Disc 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. Engineered specifically for disc brakes, it's compatible with a 12x100 axle up front, and 12x142 rear, and can convert to Quick Release with supplied adapters. It's available for Shimano and Sram XD-Road cassettes, and can convert to Campagnolo with an optional driver body.
For Center Lock disc rotors only.

Key technology

LightnessMaxtal aluminum alloy
Light and strong. Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.
LightnessISM light rim technology
Inter Spoke Milling is an exclusive Mavic patented concept. The ISM involves the machining of the lower bridge of the rim between each spoke hole to create a light and rigid rim without reducing the durability of the rim.
Efficiency RigidityFore 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.
Efficiency RigidityInstant Drive 360 freewheel technology
The new Instant Drive 360 freewheel system is super light and efficient. A large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
Efficiency RigidityUST 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.
Safety ReliabilitySUP welding technology
Soudé Usiné Process, stronger and smoother joint. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
Safety ReliabilityInfinity hub design
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The length of the spokes at the front and rear is identical. Maintenance is easy thanks to a tool-free solution.
Safety ReliabilityQRM Auto bearing preload technology
Qualité de Roulements Mavic Auto. 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.
