Originally this derailleur could be used together with an 11-speed rear derailleur, but that functionality was later removed in a firmware update. You can not longer use different speed derailleurs on the same bike.

If you are using one of these with an 11 speed rear derailleur I strongly recommend you do not update its firmware.
