Abstract

A control device for controlling at least one adjustment member, in particular an electrical chain transfer of a bicycle, is proposed. The control device comprises a signal transmitter which is disposed at a location distant from the at least one adjustment member and which can be set by a user into a plurality of shift settings, in particular gears, for setting the at least one adjustment member into a plurality of operational positions, and at least one signal line for transmitting signals between the signal transmitter and the respective adjustment member. The control device of the invention has a first signal monitoring unit, assigned to the signal transmitter and connected with the at least one signal line, for monitoring the signals to be transmitted to the at least one adjustment member, and a second signal monitoring unit per adjustment member and assigned to the respective adjustment member and also connected with the at least one signal line, for monitoring the signals transmitted by the signal transmitter.
