Abstract:
A bicycle front derailleur includes a base member, a movable member, and a chain guide with an angle adjustable plate member. The base member is configured to be coupled to a portion of a bicycle. The movable member has a first support side coupled to the base member and a second support side spaced from the first support side. The movable member is configured to move the second support side between a retracted position and an extended position relative to the base member. The angle adjustable plate member is coupled to the second support side for movement therewith. The chain guide includes a chain cage with the angle adjustable plate member operatively coupled to selectively adjust an angular orientation of the chain cage relative to the angle adjustable plate member.
