Abstract: The invention relates to a rear derailleur for a bicycle gearing system comprising: a base element which can be fitted to a bicycle frame; and a movable element which is coupled to the base element by a pivot mechanism and which can be displaced relative thereto in a pivotably movable manner, wherein the pivot mechanism is pivotably movable both relative to the movable element and relative to the base element. The rear derailleur comprises for easier adjustment of the chain tension a blocking device which is configured to at least temporarily secure the movable element relative to the base element, wherein the blocking device is configured in such a manner that the pivot mechanism can be temporarily secured by a direct coupling relative to the base element or relative to the movable element in at least one predetermined blocking position.

Abstract: The disclosure relates to an electromechanical rear derailleur for coaxial assembling on a rear wheel axle. The derailleur has a base element, a pivot mechanism, and a movable element having a chain guide assembly. The chain guide assembly is connected to the movable element so as to be rotatable about a rotation axis. A blocking device permits the chain guide assembly to be established relative to the movable element. The blocking device is able to be inserted into the movable element in two different positions.
