Shadow Rear Derailleur (12 speed)


This DURA-ACE Rear Derailleur is part of the 12 speed system, semi-wireless, and uses a new battery, the BT-DN300.

It features a charge port, LED, button, and an EW-SD300 type port used to connect the derailleur to the battery. Both the rear derailleur and the front derailleur connect to the battery using a wire.

The shift levers send their shift commands to the rear derailleur wirelessly.
