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.

Abstract: A front derailleur includes a base 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 cable guiding structure has one of bore, recess and groove formed on the link mechanism to guide the operation cable. The operation cable exits forwardly from the cable guiding structure within a sector having an angle of 150 degrees around the crank axis from an upper radius lying in a first plane that is perpendicular to a second plane containing a crank axis and a rear wheel axis.
