The front derailleur includes a base member, a chain guide, and a linkage structure. The base member includes a mounting hole. The mounting hole has a central axis. The linkage structure includes a first link member and a second link member. The first link member is pivotally coupled to the base member about a first pivot axis. The second link member is pivotally coupled to the base member about a second pivot axis. The first link member is pivotally coupled to the chain guide about a third pivot axis. The second link member is pivotally coupled to the chain guide about a fourth pivot axis. The first pivot axis, the second pivot axis, the third pivot axis and the fourth pivot axis are all not parallel to and not perpendicular to the central axis of the mounting hole.
