Product Description

Based on the technology introduced by SHIMANO with the RX rear derailleurs, the GRX RD-RX812 1x11-speed rear derailleur is characterised by quiet, smooth, precise and reliable shifting, even in the most demanding terrain, thanks mainly to the SHADOW RD+ chain stabilisation system.

It prevents the chain from hitting and unnecessary movements of the rear derailleur cage, thus ensuring uninterrupted switching performance.

SHIMANO's GRX, the first Gravel-specific component family designed for both fast progress and safe bike handling on loose surfaces, is the result of an intensive and extensive research, testing and development process that incorporates information and feedback from countless riders on trails, forest tracks, gravel tracks and asphalt all over the world.

    • Adjustable chain stabilizer prevents chain slapping and drops
    • Switch stabilizer ON/OFF to match the terrain
    • Gravel-tuned clutch tension
    • Silent and uninterrupted rear shifting on rough terrain
    • Smooth and reliable mixed surface shifting
    • Compatible with current road DUAL CONTROL LEVER


    Shimano Shadow RD+

    Less distraction quiet drive train. Rear Derailleur Stabilizer reduces chain slap. Simple solution for chain drop. Lighter and more efficient than roller type chain device.
