Shimano GRX RD-RX400 10-speed rear derailleur

The Shimano GRX RD-RX400 was specially developed for gravel and adventure bikes and offers reliable, precise shifting even under the harshest conditions. With its robust design and optimised geometry, it is perfectly matched for use with 10-speed drivetrains and cassettes up to 36 teeth. Thanks to the integrated Shadow RD+ technology, the rear derailleur reduces chain slap and ensures a smoother, quieter ride - especially on uneven surfaces. The low design also minimises the risk of damage from stones or obstacles. The GRX RD-RX400 offers smooth gear changes, whether on long climbs, fast descents or technical terrain, and combines the proven Shimano shifting precision with gravel-specific robustness.

The GRX RD-RX400 is the perfect choice for riders looking for reliability, smoothness and precise shifting performance on any terrain - from gravel tracks to challenging bikepacking adventures.
