Abstract
A rear derailleur includes a base member, a movable member, a link and a chain guide. The link is connected to the base member about a first link axis and to the movable member about a second link axis. The chain guide is mounted to the movable member about a tension pivot axis. The chain guide includes a first pulley having a first rotational axis and a second pulley having a second rotational axis. The tension pivot axis is substantially parallel to the first and second rotational axes. A first reference line defines a distance between the tension pivot axis and the first rotational axis with a range between 2 to 70 millimeters. The first link axis and a reference plane define an angle ranging from 3 to 35 degrees. The first reference line and a second reference line define an angle ranging from 20 to 170 degrees.
