This junction kit is equipped with connectors for ST-9071, SW-9071, SW_R671 or SW-R600. One additional port is used to connect to the optional EW-SD50 wire kit, which then connects the battery-pack, front and rear derailleur.

The additional wire kit EW-SD50 is required for operation.

Note: In order to ensure proper functioning of the electronic Di2 drive system, all components require the same firmware version. The optional diagnostic device allows for reading out or updating the firmware version. An operation of components with different firmware versions may cause a malfunction or loss of function.
