Shimano Cage Lock Maintenance Tool

This is a little tool to keep the cage of Shimano 6100 Deore, 7100 SLX, 8100 XT, and 9100 XTR derailleurs locked in a retracted position to make bike maintenance easier. Including removing the rear wheel, Cleaning, replacing the chain, etc. It serves the same purpose as the cage lock that is built into SRAM derailleurs.
