Abstract:
1. A bicycle control system comprising: a first switch device including a first switch operation member, a first sensor arranged relative to the first switch operation member to detect operation of the first switch operation member, a first processing unit operatively coupled to the first sensor and a first transmitter arranged to periodically transmit first output signals at first prescribed transmission timings; a second switch device including a second switch operation member, a second sensor arranged relative to the second switch operation member to detect operation of the second switch operation member, a second processing unit operatively coupled to the second sensor and a second transmitter arranged to periodically transmit second output signals at second prescribed transmission timings; and a cycle computer including a receiver arranged to receive the output signals from the transmitters of the first and second switch devices, the first processing unit of the first switch device including the second processing unit of the second switch device including with the first and second prescribed transmission timings being such that the first and second output signals are sent to the cycle computer at recurring prescribed intervals in a non-overlapping manner, the first operating signal generating member generating time lag data as part of the first operation codes in response to an operation of the first switch operating member which occurs prior to a subsequent one of the starting points of the first prescribed transmission timings and which is not transmitted with the only one of the first operation codes transmitted after a starting point immediately preceding the subsequent one of the starting points of the first prescribed transmission timings.
