摘要： An electric front derailleur includes a base member, a chain guide, a first link member, a second link member and an electric driving unit. The base member includes a mounting portion to be operatively mounted to a bicycle frame. The chain guide is movable with respect to the base member. The first link member movably connects the chain guide to the base member. The first link member is at least partially aligned with the chain guide in a lateral direction with the electric front derailleur in an installed position. The second link member movably connects the chain guide to the base member. The second link member is at least partially aligned with the chain guide in the lateral direction with the electric front derailleur in the installed position. The electric driving unit is operatively coupled to the chain guide to move the chain guide with respect to the base member.

摘要： A bicycle front derailleur is basically provided with a base member, a movable member, an electric driving unit and a biasing member. The base member includes a bicycle mounting portion. The movable member is movably supported 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 electric driving unit is operatively coupled to the movable member to move the movable member between the first position and the second position. The biasing member is operatively disposed between the base member and the movable member to bias the movable member towards the second position.

摘要： A front derailleur is provided with a base member, a linkage assembly, a chain guide, an input link, a connecting link and an outer casing receiving part. The linkage assembly includes a first link coupled to the base member at a first pivot axis, a second link coupled to the base member at a second pivot axis, and an extension link coupled to the first link and the base member. The chain guide is coupled to the first and second links. The input link, is supported relative to the base member about a third pivot axis, and connects to an operation cable. The connecting link is connected to the input link about a fourth pivot axis and to the extension link about a fifth pivot axis. The outer casing receiving part is disposed on the base member and receives an outer casing through which the operation cable passes.

摘要： A front derailleur is attachable to a bicycle with a frame in which a fixing bore is provided. The front derailleur basically includes a base member, a chain guide and a link mechanism. The base member has an attaching bore for attaching the base member to a fixing bore of a frame by a fastening member. The chain guide configured to guide a chain. The link mechanism movably couples the chain guide to the base member. The base member is disposed with respect to the chain guide such that at least a part of the attaching bore is disposed in front of the chain guide and above the chain guide while the front derailleur is in a state in which the base member is attached to the frame.

摘要： 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.
