Shadow Rear Derailleur (12 speed)
This 105 R7150 Rear Derailleur was announced by Shimano in July 2022. It is part of the 105 12 speed Di2 system, semi-wireless and uses the BT-DN300 battery.
This derailleur 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.
The low sprocket maximum is 36T.
These 12-speed derailleurs use the same charger as the DURA-ACE and Ultegra Di2 power meters, and perhaps even better: the port cover can be replaced when broken.
