Abstract
A linear derailleur for positioning a drive chain in response to displacement of a plurality of control cables. The derailleur includes a linear actuator having a substantially uniform actuation ratio over the range of motion of the actuator and, hence, derailleur. The linear actuator also has a mean actuation ratio over its range of motion equal to Cos .theta.:1, where .theta. equals the angle of inclination of the actuator.
