Abstract
A hand-operated shift actuator (16) displaces a derailleur control cable (22). The actuator (16) includes a stationary member (60) that is affixed relative to a bicycle handlebar (44). Rotation of the rotating member (62) causes the control cable (22) to be displaced, thus actuating the derailleur (24) to which the control cable (22) is attached. A plurality of detent positions (104-115) each correspond to a derailleur overshift position. The rotating member (62) is rotatable in a first direction to any of these detent positions (104-114). A spring-loaded overshift corrector (90, 142) urges the rotating member (62) from an overshift position in a second direction to a respective new desired sprocket center position when the rotating member (62) is released by the hand of the rider.
