$80 · 2019 Shimano Ultegra R8000 GS Shadow 11 speed Rear Derailleur

Shimano Ultegra R8000 GS (long cage) Shadow 11 speed rear derailleur. The Shadow design helps keep the derailleur out of harm's way, should your bike take a tumble. Lightweight aluminum pulley cage helps reduce weight without affecting performance. Maximum sprocket capacity is 34T. Minimum sprocket capacity is 11T. Maximum front difference is 16T. Total capacity is 39T. Taken off my new bike after riding once for 20 miles, then replaced with an RX800 RD. Looks and performs like new. Located in Duncan.
