Mavic Ksyrium SL Disc Heritage Wheelset 2026

The Mavic Ksyrium SL Disc Heritage wheelset is much more than a simple pair of wheels: it is a modern tribute to the brand's legendary wheels, combining an iconic neo-retro style with the most advanced performance technologies. Inspired by Mavic's history, this wheelset features a distinctive aluminium finish.

Designed to excel in training and competition alike, they are the benchmark for lightness and durability in the aluminium wheel category. Thanks to the lightweight ISM4D Maxtal alloy rim, and the Fore technology which eliminates the need for rim tape (weight saving and increased airtightness), they offer remarkable lateral stiffness for maximum power transfer, while maintaining essential vertical compliance for long-distance comfort.

The Infinity hub with the Instant Drive 360 (ID360) freewheel ensures ultra-fast engagement and total reliability, while the optimised UST Road Tubeless system provides speed, comfort, and better control, without the risk of pinch flats. This is the ideal wheelset for demanding cyclists looking for modern performance with a timeless aesthetic.
