Shimano RD-R7150 105 Di2 Rear Derailleur One-Spec Features
The RD-R7150 12-speed rear derailleur is the central element of the Shimano 105 Di2 road bike groupset when it comes to semi-wireless shifting. It has even more to offer than a conventional rear derailleur, since it communicates wirelessly with the shift/brake levers via the built-in wireless chip in the disc brake version.

- Check the battery level and Bluetooth/ANT pairing success with your cycle computer/smartphone/tablet
