Mavic Ksyrium SL Rim Brake, Wheelset

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.

MAIN FEATURES

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, saves 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 plaform: 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 means less friction, better efficiency and grip, a 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.
