Shimano RD-R9150/RD-R8050 Di2 rear derailleur bracket axle unit for normal type rear derailleur. This is the link on the newer Shimano rear derailleurs ex. RD-R9150/RD-R8050. Perfect to keep as a spare if the one on the bike fails.
- if your rear derailleur is a type of 'direct mount' ex. some of our Pinarello F10 and some Cannondale's, you can use this bracket axle unit to mount the rear derailleur on a normal gear drop. You will still need the B-Axle screw which is not included
- As new - have been mounted on a rear derailleur
