Mavic Ksyrium SL Disc Heritage Rear 2026

The Mavic Ksyrium SL Disc Heritage rear wheel is far more than a simple wheel: 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 heritage, this rear wheel features a distinctive aluminium finish.

Designed to excel in both training and racing, it stands as a benchmark for lightness and durability in the aluminium wheel category. Thanks to the lightweight ISM4D Maxtal alloy rim and the Fore technology eliminating the need for rim tape (for weight savings and improved sealing), it delivers outstanding lateral stiffness for maximum power transfer, while maintaining essential vertical compliance for long-distance comfort.

The Infinity hub with Instant Drive 360 (ID360) freewheel ensures ultra-fast engagement and flawless reliability, while the optimised UST Road Tubeless system provides speed, comfort and better control with no risk of pinch flats. It is the ideal wheel for demanding cyclists seeking modern performance with timeless aesthetics.
