Description:
This chain guide should be installed on every bike. It keeps the chain from falling in case of an over-shift. If you over-shift the front derailleur or shift too fast or the chain just bounces off for no apparent reason, the aluminium alloy guide catches the chain and keeps it up and from falling down to the bottom bracket shell.
