This Shimano RD-R9150 Outer Plate and Fixing Bolt is a genuine replacement part for the Dura-Ace Di2 rear derailleur. It includes the outer cage plate along with the fixing bolt that secures it to the derailleur body. The part fits the RD-R9150 short cage model built for 2x11 speed drivetrains, matching factory specifications for a proper reinstall.
Riders who damage the outer cage plate through a crash or chain mishap can restore proper shifting function without replacing the entire derailleur. The inner cage, pulleys, and derailleur body are sold separately, so this part addresses only the outer plate assembly. It offers a straightforward option for shops and home mechanics completing a targeted repair on an existing Dura-Ace Di2 setup.
