When the external device E is connected to the first wireless communication unit 36, the external device E requests the first wireless communication unit 36 for identification information in step S11. The first wireless communication unit 36 that has received the signal requesting identification information (hereinafter referred to as "identification information request signal") requests the control unit 56 for identification information in step S12. The control unit 56 that has received the identification information request signal reads the identification information stored in the first storage unit 136 in step S13 and transmits the identification information to the first wireless communication unit 36. The first wireless communication unit 36 that has transmitted the identification information transmits the identification information to the external device E in step S14.

The external device E having received the identification information displays an electric component corresponding to the received identification information on a display unit (not shown) in step S15. The model of the front derailleur 32 is specifically shown. In this case, when there are a plurality of electrical components that can communicate with the first wireless communication unit 36, the external device E can list all the electrical components that can communicate with the first wireless communication unit 36. In addition, when the external device E can communicate with the second wireless communication unit 40, the external device E can also include and display a list of electrical components that can communicate with the second wireless communication unit 40.

The user selects the front derailleur 32 using an operating unit (not shown) according to the display content of a display unit (not shown) of the external device E. The operation unit is, for example, a touch panel or a keyboard provided in the display unit.

When the user selects the front derailleur 32 via the operation unit (not shown) in the external device E, the individual information is requested to the first wireless communication unit 36 in step S16. The first wireless communication unit 36 that has received the signal requesting the individual information (hereinafter referred to as "individual information request signal") requests the control unit 56 for the individual information in step S17. The control unit 56 that has received the individual information request signal reads the individual information from the first storage unit 136 and transmits the individual information to the first wireless communication unit 36 in step S18. The first wireless communication unit 36 that has received the individual information transmits the individual information to the external device E in step S19.

The external device E that has received the individual information displays the individual information received in step S20 on a display unit (not shown). The user selects individual information using an operation unit (not shown) according to the display content of a display unit (not shown) of the external device E. When the user performs an operation to change the individual information, the external device E transmits a signal requesting update of the individual information (hereinafter referred to as "individual information update request signal") to the first wireless communication unit 36 in step S21. The individual information update request signal is, for example, a signal intended to be a request to change the first movable member 54 to the first direction or the second direction in the adjustment setting of the front derailleur 32.

The first wireless communication unit 36 that has received the individual information update request signal transmits the individual information update request signal to the control unit 56 in step S22. The control unit 56 that has received the individual information update request signal updates the individual information stored in the first storage unit 136 based on the individual information update request signal in step S23. That is, the front derailleur 32 updates the information stored in the first storage 136 based on the communication with the first wireless communication unit 36. In step S23, the control unit 56 operates the first actuator 58 based on the individual information update request signal. When the individual information update request signal is the adjustment setting of the front derailleur 32, the control unit 56 actuates the first actuator 58 based on the individual information update request. That is, the front derailleur 32 actuates the first actuator 58 based on a signal from the first wireless communication unit 36.

After step S23, the update process is terminated by an operation of an operation unit (not shown) of the external device E, or at least one of steps S11 to S23 is executed again. For example, when the user performs an operation to update other individual information of front derailleur 32, the processing of steps S16-S23 is executed again. When the user further updates the updated individual information in step S23, the processing of step S21 to step S23 is executed again.

The process of updating the information stored in the second storage unit 138 is also the same as the process of updating the information stored in the first storage unit 136. For example, in the process according to step S21, when the individual information update request signal is transmitted from the external terminal E to the second wireless communication unit 40, the second wireless communication unit 40 that has received the individual information update request signal transmits the individual information update request signal to the control unit 66. The control unit 66 that has received the individual information update request signal updates the individual information stored in the second storage unit 138 based on the individual information update request signal. The rear derailleur 34 updates the information stored in the second storage unit 138 based on communication with the second wireless communication unit 40. The control unit 66 operates the second actuator 68 based on the individual information update request signal. When the individual information update request signal is the adjustment setting of the rear derailleur 34, the control unit 66 actuates the second actuator 68 based on the individual information update request signal. That is, the rear derailleur 34 actuates the second actuator 68 based on the signal from the second wireless communication unit 40. According to the electric system 30 of the seventh embodiment, at least the effects (1) and (2) according to the first embodiment can be exerted.
