Shimano Tourney RD-TY300-SGS 6/7 speed rear derailleur

The Shimano Tourney RD-TY300-SGS rear derailleur is designed for Shimano SIS INDEX 6- and 7-speed drivetrains. With its direct mount, SGS cage, and compatibility with HG 8, 7, and 6-speed chains, it provides a reliable solution for servicing or replacing a rear derailleur on a compatible bicycle.

Versatile and accessible, the Shimano Tourney RD-TY300-SGS - ERDTY300D rear derailleur ensures simple and efficient gear changes on entry-level leisure bikes, hybrid bikes, city bikes or mountain bikes equipped with a Shimano 6 or 7 speed transmission.
