Shimano Sora RD-R3000-GS 9-Speed Road Bike Rear Derailleur (Medium Cage)

Bring premium styling and extended versatility to your 9-speed drivetrain with the Shimano Sora RD-R3000-GS Rear Derailleur. As the centerpiece of Shimano’s robust Sora R3000 sports groupset, this derailleur delivers the reliable mechanical precision everyday commuters, fitness riders, and weekend tourers depend on.

The GS (Medium Cage) configuration is optimized for wide-range setups.
