Abstract: A bicycle derailleur is basically provided with a base member, a chain guide, a linkage assembly and a first adjusting member. The chain guide is pivotally supported with respect to the base member between a retracted and an extended position. The linkage assembly includes a first link coupled to the base member about a first pivot axis and coupled to the chain guide about a second pivot axis. The linkage assembly includes a second link coupling the base member to the chain guide. The second link is farther from the bicycle frame than the first link when the base member is mounted to the bicycle frame. The first adjusting member is movably attached to the first link. The first adjusting member is configured to contact one of the base member and the chain guide to restrict movement of the chain guide at one of the retracted and extended positions.

Abstract: A front derailleur is basically provided with abuse member, a chain guide, a link mechanism and a cable guiding structure. The base member is fixedly coupled to a bicycle. The chain guide is configured to guide a chain. The link mechanism movably couples the chain guide to the base member between a retracted position and an extended position in response to movement of an operation cable. The link mechanism includes a cable attachment portion that is configured to be attached to the operation cable. The cable guiding structure guides the operation cable from the cable attachment portion. The cable guiding structure is disposed on at least one of the base member and the link mechanism. The cable guiding structure has a cable exit that is arranged such that the operation cable exits forwardly from the cable guiding structure towards the front of the bicycle.

The first outer-link end portion comprises a first outer surface, a first inner surface, a first outer-link opening, and a first outer-link outermost edge. The first outer-link intermediate portion comprises a first intermediate outer surface, a first intermediate inner surface, a first outer-link intermediate outermost edge, a first additional outer-link intermediate outermost edge, and a first intermediate chamfer. The first intermediate chamfer has a first minimum distance defined between the first outer-link intermediate outermost edge and the first inner edge along a reference line. A distance defined between the first outer-link intermediate outermost edge and the first additional outer-link intermediate outermost edge on the reference line is minimum in the first outer-link intermediate portion. The first minimum distance is equal to or larger than 1 mm.
