Abstract
A front derailleur comprises a base member, a chain guide, and a linkage structure. The base member includes a mounting hole. The mounting hole has a center axis. The linkage structure comprises 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. At least three of the first pivot axis, the second pivot axis, the third pivot axis, and the fourth pivot axis are non-parallel to and non-perpendicular to the center axis of the mounting hole.
