Abstract:
1. A front derailleur attachable to a bicycle having a crank axis and a rear wheel axis which is parallel to the crank axis, the front derailleur comprising: a base member configured to be fixedly coupled to the bicycle to install the front derailleur on the bicycle; a chain guide configured to guide a chain, the chain guide having an upstream end and a downstream end, the downstream end being disposed forward of the upstream end in a longitudinal direction of the bicycle while the front derailleur is in an installed state on the bicycle; a link mechanism movably coupling 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 including a cable attachment portion that is configured to be attached to the operation cable; and a cable guiding structure configured to guide the operation cable from the cable attachment portion, the cable guiding structure being disposed on at least one of the base member and the link mechanism, the cable guiding structure having a cable exit that is arranged such that the operation cable exits forwardly from the cable guiding structure along a cable exit axis, the cable exit axis extending into a sector having an angle of 150 degrees around the crank axis from a first plane that is perpendicular to a second plane containing the crank axis and the rear wheel axis while the front derailleur is in an installed state on the bicycle, the sector being disposed on a forward side of the first plane in the longitudinal direction of the bicycle and spanning angularly from a portion of the first plane disposed above the second plane toward a portion of the first plane disposed below the second plane in a side view of the bicycle, the cable exit being disposed above the crank axis while the front derailleur is in an installed state on the bicycle.
