Abstract: A bicycle derailleur is basically provided with a base member, a movable member and a connecting structure. The base member includes a bicycle mounting portion. The movable member is movable with respect to the base member between a first position and a second position that is farther than the first position from the base member. The connecting structure movably connects the movable member to the base member. The connecting structure moves the movable member with an actuation ratio that descends and then ascends as the movable member moves from the first position towards the second position.

Abstract: A bicycle front derailleur is provided that can be easily coupled to a bicycle frame. The bicycle front derailleur includes a base member, a chain guide and a link mechanism. The base member is configured to be coupled to a bottom bracket hanger of the bicycle frame. The chain guide is configured to guide a chain. The link mechanism connects the chain guide to the base member to move the chain guide between a retracted position and an extended position. The base member includes a recess configured to accommodate a part of the chain guide in a state where the chain guide is located at the retracted position.

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.

Abstract: A component assembly for a human-powered vehicle, the component assembly basically includes a member and a wire rod. The member includes a wall that has a first surface, a second surface opposite the first surface and an opening. The wire rod passes through the opening in the wall of the member. The wire rod includes a first portion located on the first surface side of the wall and a second portion located on the second surface side of the wall. The first portion includes an abutment portion that contacts the first surface adjacent the opening in the wall to suppress axial movement of the first portion of the wire rod through the opening in the wall with respect to an axial direction with respect to a center axis of the opening in the wall.

Abstract: A hub assembly is provided for a human-powered vehicle. The hub assembly includes a hub axle, a hub body, a cable and a cable protector. The hub axle has a first axial end and a second axial end. The hub body is rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly. The cable has a first portion disposed inside of the hub assembly and a second portion disposed outside of the hub assembly. The cable protector is movably arranged between a first position and a second position. The second portion of the cable extends along the rotational center axis where the cable protector is in the first position. The second portion of the cable being at least partly restrained in an angled position with respect to the rotational center axis where the cable protector is in the second position.
