Abstract
A bicycle derailleur is provided with a parallelogram link that is sufficiently rigid axially to maintain the distance between the link pivot axes during derailleur actuation but substantially flexible in torsion and shear to permit simple alignment of the pivot holes and control of the link width during formation and assembly of the link, thereby ensuring smooth operation of the derailleur during gear shifts.
