Abstract: A bicycle front derailleur includes a mounting member, a chain guide, and a linkage assembly that pivotally couples the mounting member to the chain guide. The mounting member is configured to be mounted to a first frame member of a bicycle frame. The first frame member is pivotally connected to a second frame member of the bicycle frame about a pivot axis. The mounting member includes an attachment portion through which a fixing bolt for fixing the mounting member to the first frame member passes and includes an abutment configured to restrict rotation of the mounting member around the fixing bolt. The attachment portion is located on a front side of the pivot axis when the mounting member is mounted to the first frame member. The bicycle frame includes a structure for engaging and supporting the mounting member.

Abstract: A bicycle derailleur has a base member, a movable member, a first link member and a second link member. The movable member is movable with respect to the base member between a retracted position and an extended position. The first link member includes a first connecting portion pivotally coupled to the movable member about a first pivot axis. The first link member is pivotally coupled to the base member about a second pivot axis. The second link member is pivotally coupled to the movable member about a third pivot axis. The second link member is pivotally coupled to the base member about a fourth pivot axis. The first connecting portion at least partially overlaps with the second link member as viewed in a direction parallel to the first pivot axis in a state in which the movable member is disposed at one of the retracted and extended positions.

Abstract: A front derailleur basically includes a fixed member, a main body, a movable member and a support member. The fixing member is configured to be fixed to a bicycle frame. The main body is attached to the fixing member. The movable member is movably supported to the main body with respect to the fixing member. The support member is movably attached to one of the fixing member and the main body. The support member including an operated portion selectively operated by an operating element and positioned between the fixing member and the main body.

Abstract: A front derailleur basically includes a fixed member, a movable member, a driven link and a first link. The fixing member is configured to be fixed to a bicycle frame. The movable member is movably supported with respect to the fixed member. The driven link is operatively coupled to the movable member. The first link movably connects the movable member to the fixed member, and is adjustably coupled to the driven link in a fixed position by a fixing structure to establish a fixed rest position of the movable member with respect to the fixed member.
