Abstract
A bicycle transmission control apparatus comprises a control unit that provides a first signal to operate a first derailleur a gear shift distance from a first origin sprocket to a first destination sprocket. The control unit receives a condition signal that indicates a condition resulting from at least one of the first derailleur and a second derailleur; and an adjustment controller moves the first derailleur an adjustment distance less than the gear shift distance in response to the condition signal.
