  • Patent number: 7892122
    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.

  • Patent number: 7874567
    Abstract: A bicycle shifting control apparatus controls an electrical power supplied from a power supply to first and second gear shifting devices that are operated by first and second gear shift operating devices, respectively. The bicycle shifting control apparatus includes a first power supply sensor and a controller. The first power supply sensor detects a power level of the power supply. The controller receives a power level signal from the first power supply sensor. The controller performs a stopping operation of the first gear shifting device in response to the first power supply sensor detecting the power level of the power supply being below a first prescribed power level, but the controller transmits a second gear shift signal from the second gear shift operating device to the second gear shifting device to perform a second shifting operation of the second gear shifting device.
