Shimano Tourney RD-TY500-SGS Rear Derailleur | 6/7-Speed | Long Cage | Direct Mount | Black
Shimano Tourney RD-TY500-SGS Rear Derailleur | 6/7-Speed | Long Cage
Dependable entry-level Shimano shifting for recreational, commuter, comfort, and mountain bikes.
The Shimano Tourney RD-TY500-SGS Rear Derailleur is a practical replacement for compatible 6- and 7-speed bicycle drivetrains. Its SGS long-cage design supports wider gearing and provides the chain capacity needed for many triple-chainring and MegaRange-equipped bicycles.
This version uses Shimano’s rear direct-mount configuration with a standard 10 x 1 mounting interface. Before ordering, compare the mounting arrangement with your existing derailleur and frame hanger to confirm compatibility.
The TY-series construction uses a resin bracket and plate body to control weight, while zinc-plated adjustment screws improve corrosion resistance. With support for rear cogs up to 34 teeth and a 43-tooth chain-wrap capacity, the RD-TY500-SGS is well suited to everyday bicycles that need affordable, reliable shifting.
