Shimano SLX RD-M7100-SGS Rear Derailleur 12-Speed

The Shimano SLX RD-M7100-SGS is a 12-speed rear derailleur designed for MTB 1x12 drivetrains, delivering precise, fast and stable shifting performance even on demanding terrain.

Thanks to SHADOW RD+ technology, chain movement and vibration are reduced, improving drivetrain stability on rough trails and reducing the risk of chain drop.

The low-profile design protects the derailleur from impacts, while compatibility with wide-range cassettes (up to 10-51T) makes it ideal for modern trail, XC and light enduro MTB setups.
