Abstract: A rear derailleur is basically provided with a base member, a movable member, a chain guide, a friction element, a one-way clutch and an electric actuator. The base member is configured to be mounted to a bicycle. The movable member is movably coupled to the base member. The chain guide is coupled to the movable member to rotate around a rotational axis with respect to the movable member. The friction element is operatively arranged between the movable member and the chain guide to frictionally provide rotational resistance in a first rotational direction of the chain guide. The one-way clutch is operatively disposed between movable member and the chain guide to engage the friction element as the chain guide rotates in the first rotational direction. The electric actuator is operatively coupled to the one-way clutch to control the one-way clutch between a clutch-on mode and a clutch-off mode.

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.
