Abstract
A front derailleur has a base member adapted to be coupled to a bicycle frame, a chain guide, first and second pivotal links coupled between the base member and the chain guide, and a biasing member normally biasing the chain guide toward a first position. The biasing member is disposed on a pivot axis pivotally coupling the first link to the chain guide to be at least partially located in front of the part of the first link coupled to the base member. The first link is preferably an inner link located closer to the frame than the second link. Preferably, portions of the first link are at least partially offset due to a transitional portion arranged between them. Preferably, the second link includes a cable attachment portion and a pair of axially spaced mounting elements pivotally coupled to ends of an attachment element of the base member.
