The Shimano GRX RD-RX812 derailleur is designed for gravel bikes to ensure stable and precise shifting even on challenging terrain. This 11-speed derailleur uses Shadow+ technology for quieter chain operation and better stability on uneven surfaces. Thanks to direct mounting, the component is easier to attach to a compatible frame and is simultaneously better protected near the cassette. The model supports cassettes with a range from 11 to 42 teeth.

  • Shadow+ technology for a more stable chain
  • Direct mounting
  • Support for cassettes with the largest cog up to 42 teeth
  • Model designation RD-RX812
