ABSTRACT:
A derailleur includes a motor that drives a drive member, a driven member driven by the drive member, and a clutch having a first element that disengages from a second element when substantial resistance exists in a power transmission path between the drive member and the driven member. An apparatus for controlling the derailleur comprises a re-engage command receiving circuit and a re-engagement circuit, wherein the re-engage command receiving circuit receives a re-engage command signal to re-engage the first element with the second element when the first element is disengaged from the second element, and the re-engagement circuit re-engages the first element with the second element in response to the re-engage command signal.
