Abstract
The invention provides a wireless control system for a bicycle, including at least one shift actuator generating an input signal when actuated and a master control unit transmitting a shift signal responsive to the input signal. At least one electromechanical gear changer is provided and includes a gear changer control unit. The gear changer control unit receives the shift signal from the master control unit and controls the at least one electromechanical gear changer corresponding to the received shift signal. The gear changer control unit listens for the shift signal during a part of an awake mode cycle time, the master control unit transmitting the shift signal for a message duration time which is greater than the awake mode cycle time.
