Shadow Rear Derailleur (12 speed)

Ultegra RD-R8150

The RD-R8150 rear derailleur is part of Shimano's new 12 speed system, allowing for both wired and wireless communication between the derailleur and shift levers.

It is used with the newer battery, the BT-DN300.

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.
