Abstract:
A bicycle front derailleur is basically provided with a base member, a chain guide and a chain restricting abutment. The base member is configured to be mounted on a bicycle frame. The chain guide is configured to be movably coupled to the base member between a retracted position and an extended position to move a bicycle chain. The chain restricting abutment is configured to restrict the bicycle chain from moving in a radially outward direction of a rotational center axis of a bicycle front sprocket when the base member is mounted on the bicycle frame and the chain guide moves from the extended position toward the retracted position.
