The Shimano SLX RD-M7100-SGS rear derailleur provides fast and precise shifting performance across a wide gear range. Guide and tension pulleys with 13 teeth and an integrated rubber damper reduce noise and increase riding comfort. These features also improve chain retention in all riding conditions.

The RD-M7100 rear derailleur for the SLX 1x12-speed drivetrain is suitable for use with both the wide-range 10–51 teeth cassette and the smaller 10–45 teeth Shimano CS-M7100 cassette.
