This is an unused Shimano Tourney RD-TY300 rear derailleur, suitable for 6-speed and 7-speed drivetrains. A reliable entry-level component from Shimano, designed for smooth and stable shifting for city, commuter, and recreational bicycles. The derailleur is unused and comes with its original box and instruction manual. The outer box shows some wear and deformation from storage, but the derailleur itself remains in unused condition. Please refer to the photos for exact condition details. A practical and dependable Shimano component, ideal as a replacement part or for a bicycle build.
