The Mavic FTS-L HG11 freehub body (ref. 30871101) is the official replacement part to keep your Mavic road and MTB wheels in perfect working condition. Designed by the legendary French manufacturer, this forged steel freehub body guarantees smooth transmission and universal compatibility with Shimano and SRAM cassettes from 8 to 11 speeds. An essential component of the FTS-L (Free To Spin - Light) system, it ensures the instant engagement and reliability expected from Mavic equipment.

Extended compatibility and versatility

This freehub body is exclusively installed on Mavic wheels equipped with the FTS-L system, mainly road models manufactured since 2002: Ksyrium, Ksyrium Elite, Ksyrium Pro, Ksyrium SL, Aksium, Cosmic, Cosmic Elite, Cosmic Pro, R-SYS and their variations. It is also compatible with certain Mavic MTB wheels such as Crosstrail and Crossride. HyperGlide (HG) technology allows the mounting of Shimano and SRAM cassettes from 8, 9, 10 and 11 speeds, offering maximum flexibility during drivetrain upgrades or replacements.

Adaptable axle system and simplified installation

• Dual axle compatibility: Works with 8mm and 9mm axles thanks to the supplied silver adapter/spacer. For older road wheels with 8mm axle, the spacer must be installed.
• Quick installation: The FTS-L system allows easy removal and reinstallation of the freehub body without complex specialized tools. Ideal for preventive maintenance or replacement due to wear.
• Supplied without locknut: Use the locknut from your old freehub body or order it separately if necessary.

Robust construction and Mavic reliability

Made from high-quality hardened steel, this freehub body weighs 127 grams and offers optimal resistance to the mechanical stresses of the drivetrain. The splined HyperGlide profile ensures precise cassette positioning and efficient power transfer. The pawls and springs of the FTS-L hub (sold separately) guarantee the immediate engagement and free rolling characteristic of Mavic wheels.

Key technical points

• Original Mavic part: Official reference 30871101, succeeds reference M40592. Manufactured in France by Mavic group.
• Lightweight: Only 127 grams to preserve the performance of your high-end wheels.
• Black finish: Discreet and professional appearance blending harmoniously with Mavic aesthetics.

Recommended applications

This freehub body is perfectly suited for preventive replacement after several years of intensive use, drivetrain conversion (switching from Campagnolo to Shimano/SRAM for example), or emergency repair in case of breakage or seizing. Compatible with road and certain MTB models, it is intended for demanding cyclists wishing to maintain their Mavic wheels at the highest performance level. For Ksyrium 30 Disc wheels and recent models with ID360 (Instant Drive 360) system, check compatibility as other references may be required.
