ABSTRACT:
A derailleur for a bicycle comprises a base member, a movable member for supporting a chain guide, a linkage mechanism coupling the base member to the movable member, an electrically operated actuating element, and a power storing mechanism. Moving the actuating element causes the movable member to move laterally. A first portion of the power storing mechanism is disposed in a first power transmission path between the actuating element and the movable member, and a second portion of the power storing mechanism is disposed in a different second power transmission path between the actuating element and the movable member. The actuating element comprises a first actuating member and a second actuating member. The first actuating member communicates force in the first power transmission path, the second actuating member communicates force in the second power transmission path, and the first actuating member moves relative to the second actuating member.
