Abstract
A front derailleur that includes a variable attachment to a mounting socket of a bicycle frame. The front derailleur includes a base member, a chain cage, a parallelogram and an attachment member. The base member includes first and second pivot points and at least two attachment points. The parallelogram includes two parallelogram arms, each having first and second ends. The first ends are pivotable about the first and second pivot points of the base member and the second ends support the chain cage. The attachment member connects the base member to the mounting socket of the bicycle frame through one of the at least two attachment positions. The base member also includes a contact surface for mating with the mounting socket. The different attachment positions allow the position of the front derailleur to be adapted to a standard or compact set of chainrings.
