Abstract
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.

A rear derailleur device for a bicycle shifting system, comprising:
- a base body fastenable to a bicycle frame;
- a movable element coupled to the base body and displaceable in relation thereto;
- a chain guide device coupled to the movable element and pivotable around a pivot axis;
- a first biasing element by which the chain guide device is biased around the pivot axis in a starting position in relation to the movable element, wherein the chain guide device is pivotable against the bias of the first biasing element from the starting position in different operating positions around the pivot axis;
- and
- at least one locking device for locking the chain guide device in at least one locking position that is different from the starting position in relation to the movable element,
- the locking device including a locking element displaceable between a passive position, in which the chain guide device is released in relation to the movable element, and at least one active position, in which the chain guide device is held in the at least one locking position.
