The original SHIMANO RD-TY300 rear derailleur is packed in a resealable bag instead of retail cardboard packaging.
This version is not compatible with bicycle frames that have a replaceable derailleur hanger. Before purchasing, visually inspect your bicycle or check its specifications. If your bicycle has a replaceable hanger, choose the RD-TY300D derailleur version.
For smooth operation, the entire drivetrain must be adjusted correctly and maintained regularly.
