Shimano akkumulátor Di2 BT-DN300 nyeregcső nyereg vázcsőbe építhető Li-ion akku

Product description Shimano Di2 BT-DN300 Seatpost Internal Battery

The new DN300 battery features the same waterproof design that Di2 users have loved for generations. Now with 3 ports, it delivers stable power to Shimano´s 12-speed road derailleurs and shifters (if a fully wired option is selected).

With the same size as its predecessor, the slim DN300 battery can be housed inside seat posts or frames ensuring a clean aesthetic. Now with 3 ports, the DN300 simplifies wiring to front and rear derailleurs, supplying stable power at all times. The third port is for riders who seek the redundancy of Shimano´s 12-speed Di2 wired option.
