With the same size as the previous model, the slim Dn300 battery can be housed inside the seatpost or frame for a more aesthetic look. Now with 3 ports, the Dn300 battery simplifies the wiring of front and rear derailleurs, and provides stable power at all times. the third port is for cyclists who want to keep the wired option shimano di2 12 speed.
