KSYRIUM SL DISC
Ever wondered what the world’s best alloy road wheel might look like? Lightweight but durable, laterally stiff but vertically compliant, confident braking, and easy tubeless compatibility—it’s all here in the all-new Ksyrium SL Disc.
Ksyrium has always represented the best of aluminum wheel technology. Following in the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the all-new Ksyrium SL Disc lives up to that standard. If you're looking for one aluminum wheelset for weekend races and training mileage, wherever the road takes you, this is your best choice.
This new wheel is superlight (120g lighter than the former Ksyrium Elite UST Disc) and as durable as ever thanks to our patented ISM4D technology. This manufacturing process removes all excess material between each spoke hole while keeping the rim wall thick enough where spoke tension and stress is the highest. Those rims are made in France, in our aluminum rim factory.
The double-butted spokes contribute to the weight reduction while making the wheel more responsive. These spokes also have a patented elliptical shape that can save 5 watts for added efficiency.
Stiffness is optimized using Fore technology. The upper bridge is not drilled, so it remains strong and rigid and doesn’t require the use of rim tape (another 30g saved 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. 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. Engineered specifically for disc brakes, the wheels are compatible with a 12x100 axle up front, and 12x142 rear and can convert to Quick Release with supplied adapters. For Center Lock disc rotors only. It's available for Shimano or Sram XD-Road cassettes and can convert to Campagnolo with an optional driver body.
KEY BENEFITS
Superlight and durable for everyday performance
ISM4D rim weighs only 400g Patented lightweight aero spokes and 22mm deep/19mm wide rims keep inertia low and control high Solid upper rim bridge eliminates the need for rim tape, saving 60g.
Laterally stiff, vertically compliant for a more dynamic ride
Fore technology keeps the rim upper bridge solid to make the rim stiffer New Infinity hub platform: stiff axle, durable bearings, and new hub design guarantees wheel stability ID360 freewheel technology for improved power transfer.
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, 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.

Intended use
Delivered with
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.
Instant 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.
QRM Auto bearing preload Technology
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 in the long run.
ISM 4D Light Rim Technology
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 reduce aerodynamic drag
Maxtal Aluminum Alloy
Light and strong Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloys.
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.
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.
