Chain Guide Reviews

A chain guide is designed to keep the chain in the correct gear, even when the mountain bike is bouncing around in rough terrain. Chain guides come in all different shapes and sizes, but they all serve the same purpose.

However, the advent of clutch-style rear derailleurs has made chain guides all but obsolete on newer drivetrains. Some gravity riders still tend to use them even in conjunction with a clutch-style rear derailleur, however.
