Shimano Switch Lever Unit & Fix Plate – RD-M7000
The Shimano Switch Lever Unit & Fix Plate (Y5YX98040) is a small internal clutch-control service part used inside Shimano SLX RD-M7000 rear derailleurs. It is part of the mechanism that controls the derailleur’s ON/OFF clutch (stabilizer) system.
What Is It
