Mavic Ksyrium SL Heritage Disc wheelset

A custom look for this legendary alloy wheelset that never disapoints. Disc brake version.

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 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.

Technologies

Instant Drive 360 freewheel system
The new Instant Drive 360 freewheel system is super light and efficient. A large non-contact rubber seal ensures low friction, while a wide range of end caps makes it extremely versatile.

QRM Auto automatic bearing adjustment technology
Mavic Auto bearing quality. The cartridge bearings are of course double sealed with C3 internal clearance. Their preload is automatically adjusted to ensure perfect, long-term rotation without play.

Infinity hubs
Efficient power transfer thanks to optimised non-contact spoke lacing (no noise under load) and tension distribution. The front and rear spoke lengths are identical. Maintenance is easy thanks to the tool-free solution.

Maxtal aluminium alloy
Lightweight and strong. Exclusive to Mavic, this specific aluminium alloy offers a higher strength-to-weight ratio than traditional 6106 alloy.

ISM lightweight rim technology
Strong where it counts, light elsewhere

Tubeless technology without tape for Fore rims
More rigid and resistant. Instead of being drilled, the lower bridge of the rim is pushed upwards inside, then threaded to allow the spoke nipples to be screwed directly into it, leaving the upper bridge of the rim intact.

SUP welding technology
Soudé Usiné process, stronger and smoother joint. After bending, the rim joint is arc welded. The welded joint is then milled to achieve a smooth finish.
