Welcome to the Mavic website

KSYRIUM SL
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 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 lightweight (100g lighter than the former Ksyrium Elite despite its wider rim) and 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 further reduce weight 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 a rim tape (another 30g saved per rim). 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 the Instant Drive 360 freewheel coupled with our automatic bearing preload adjustment (QRM Auto) delivers fast engagement and durability.
It's available for Shimano cassettes, and can convert to Campagnolo or SRAM XD-Road with optional driver bodies.

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 4D light rim technology
Inter Spoke Milling 4 Dimensions is an exclusive Mavic patented concept. The 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.
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 RigidityIsopulse 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.
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.
