A derailleur (66, 62) for a bicycle (10) comprises a base member (400), a movable member (456) for supporting a chain guide (466), a linkage mechanism (440, 444) coupling the base member (456) to the movable member (456), an electrically operated actuating element (760, 774), and a power storing mechanism (704). Moving the actuating element (760, 774) causes the movable member (456) to move laterally. A first portion (732) of the power storing mechanism (704) is disposed in a first power transmission path between the actuating element (760, 774) and the movable member (456), and a second portion (736) of the power storing mechanism (704) is disposed in a different second power transmission path between the actuating element (760, 774) and the movable member (456). The actuating element (760, 774) comprises a first actuating member (760) and a second actuating member (774). The first actuating member (760) communicates force in the first power transmission path, the second actuating member (774) communicates force in the second power transmission path, and the first actuating member (760) moves relative to the second actuating member (774). |
