Product Description
The Shimano Tourney RD-TY300-SGS rear derailleur is a practical replacement derailleur for 6-speed and 7-speed bikes using a dropout claw hanger style mount. Designed for entry-level mountain, hybrid, and utility bikes, it uses SIS Rear Indexing and Double Servo technology for smooth shifting and accurate tracking across the cassette.
