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 aluminium wheel technology. Following in the footsteps of the venerable Ksyrium Elite and Ksyrium Pro, the Ksyrium SL takes it to the next level. It's the perfect all-rounder for those seeking a wheel that delivers reliable everyday performance on the road.
This new wheel is superlight (120g lighter than the former Ksyrium Elite UST Disc) and durable as ever thanks to Mavic's patented ISM 4D 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.
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 optimised using FORE technology. The upper bridge is not drilled, so it remains strong and rigid and does not require the use of a rim tape (another 30g saved per rim). The rim bed's shape makes it easier than ever to mount and remove tyres, and the UST tubeless technology improves rolling resistance and grip while reducing the risk of punctures. The Infinity hub platform optimises stiffness and power transfer with highly controlled spoke tension, while the Instant Drive 360 freewheel coupled with Mavic's automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability.
Key Features:
- Superlight and Durable: ISM 4D rim weighs only 400g. Patented lightweight aero spokes and 22mm deep/19mm wide rims keep inertia low and control high.
- Laterally Stiff, Vertically Compliant: FORE technology keeps the rim upper bridge solid to make the rim stiffer. Infinity hub platform with stiff axle, durable bearings, and new hub design guarantees wheel stability.
- Improved UST Road: No tubes means less friction, improved efficiency and grip with reduced risk of punctures. Rim bed shape makes it easier to mount and change tyres.
Mavic Technologies:
- Maxtal Aluminium Alloy: Light and strong. Exclusive to Mavic, this specific aluminium alloy offers a higher strength to weight ratio than the conventional 6106 alloy.
- ISM 4D Light Rim Technology: Inter Spoke Milling 4 Dimensions is an exclusive Mavic patented concept. Significantly reducing weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance. The smooth profile also helps reduce aerodynamic drag.
- 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 Technology: Super light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.
- UST Tubeless Technology: Traction and control. The UST concept improves traction, control and comfort whilst reducing inertia and flats.
- SUP Welding Technology: Soude Usine Process, stronger and smoother joint. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
- Infinity Hub Design: An ultra reliable, high performance hub. Efficient power transfer thanks to the optimised non-contact spoke lacing and tension distribution. The length of the spokes are identical on the front and rear.
- QRM Auto Bearing Preload Technology: Qualite de Roulements Mavic Auto. Cartridge bearings are double sealed with E3 internal clearance. Preload is automatically adjusted to guarantee a perfect spin with no play on the long run.
