3 to 6 Speed Rear Derailleur

This derailler is a way too cheap design. Setting screws directly mounted in plastic which obviously is not going to last long here. The scew to adjust the derailler position is so sharp that it screwed into the frame intead of pushing against it. 2nd major issue: the cage cannot be opened as the pulley are riveted! So you have to break your chain if now quick link.

This little derailleur worked perfectly for me when converting my city bike from single speed to six speed. The short design worked perfectly with 20” wheels and it performed flawlessly with a Shimano thumb shift. Very easy to set up and gear selection is smooth.

Very nice
