  • Bicycle twist-grip shift control device with parallel gearing
    Patent number: 7290462
    Abstract: A bicycle twist-grip shift control device includes a base member for attachment to the bicycle; a twist-grip operating member rotatably supported relative to the base member for rotating in first and second directions around an operating member axis; a transmission control member rotatably mounted relative to the base member for controlling the pulling and releasing of a transmission control element in response to rotation of the operating member, and an intermediate member that moves in a direction of an intermediate member axis in response to rotation of the operating member. The transmission control member rotates around a transmission control member axis that is substantially parallel to the operating member axis, and the intermediate member includes an intermediate member detent for maintaining a rotational position of the operating member and the transmission control member.
