This Box one Derailleur & shifter are sick! The derailleur is practically brand new. With one chain mark on the white part (see pictures), used for one trip! But I’m changing to a different system. The shifter isn’t knew and has lost a plastic grub screw/ cover but I’ve applied tiger seal over it and covers/seals it ok and hasn’t effected the performance (see in pictures) welcome to the cable & routing as they’ll be thrown in. The Box One 7 Speed Rear Derailleur and shifter is a high-quality component designed for smooth gear changes with 7 gears. Manufactured by Box, this rear derailleur Ideal for riders looking to upgrade their bike's performance.
