A chain guide of a bicycle derailleur for displacing a chain between gears that includes inner and outer side plates, a pivot shaft and a thermoplastic connector. The pivot shaft pivotably connects the chain guide to the bicycle derailleur. The thermoplastic connector injection molds the pivot shaft to one of the inner and outer side plates.

Bicycle derailleur

A derailleur device, particularly a rear derailleur, includes at least one locking device for locking a chain guide at least in one locking position that is different from the starting position in relation to a movable element, and it is provided therein that the locking device includes a locking element displaceable between a passive position, in which the chain guide is released in relation to the movable element, and at least one active position, in which the chain guide is held in the at least one locking position.

Rear derailleur device for a bicycle shifting system

A stable and play-free pivot connection of a bicycle derailleur between a parallelogram link and either a base member or a chain cage. The pivot points are formed with first and second bushings that are arranged as far from one another as possible. The parts are connected by pivot pins having a anti-rotation contour for preventing rotation of the pin within an inner pivot part. The axial displacement of the pivot pin is prevented by a securing element or by a deforming element engaging a holding contour on the pivot pin. One of the first and second bushings is protected and arranged in a blind hole and the other of the first and second bushings is covered on the outside by a pin head of the pivot pin.

Pivotal connection of a bicycle derailleur

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.
