SHIMANO Dura Ace Di2 Rear Derailleur RD-R9150 Shadow Short Cage
Precise gearshifts are the hallmark of any Dura Ace series. With the electronic Di2 version this feature is even more emphasized. With one operation, the chain changes the pinion without any force. Even under medium and high loads, thanks to Low Profile Design and SHIMANO Shadow RD technology, the gearshift is done quickly and without much noise. There are no noisy crashes or rattles with these high-tech components!
Due to the innovative design of the RD-R9150 rear derailleur, the wider range of cassettes with 11-30 teeth can now be used.
