Shimano Rear Derailleurs

We carry Shimano rear derailleurs for 12-speed Shimano road and gravel groupsets. Most of these derailleurs are part of Shimano’s Di2 semi-wireless drivetrains, but we also offer 12-speed mechanical GRX rear derailleurs. Each of these are compatible with Shimano 12-speed cassettes and feature Shimano’s precise, ultra-fast shifting.
