SHIMANO Akkuhalter intern | externally BM-DN 100 for Di2 battery SM-BTR1
Di2 battery holder for bottle cage mounting with cable management inside or outside the frame. For fastening serve the bottle cage bolts, the bottle holder can still be used.
The new brackets are for the Bluetooth technology that allows riders like mechanics to communicate wirelessly with the system DI2. The connection is then established between the wireless unit in the SC-MT800 (or the wireless unit WU111 EW) and a tablet or smartphone. This will allow fast configuration or troubleshooting of the Di2 system.
For a function of the system, either the new internal battery BT-DN110 or the new holder for the external battery pack (BM-DN100) is required. Furthermore, one needs as MTB riders the information display (SC-MT800), as racing cyclists the wireless unit (EW-WU111).
