2018 SHIMANO 9150 DURA ACE DI2 REAR DERRAILEUR 11SPD

SHIMANO DURA ACE 9150 DI2 REAR DERAILLEUR

Shimano's Di2 electronic shifting system is ruthlessly efficient, utterly reliable, and a pure joy to use. The development of Dura-Ace R9100, with it's R9150 Di2 components, brought about some exciting changes, such as the SynchroShift options, as well as Instant Release at the shift levers, which eliminated the intentional hesitation at the shift release before the shift took place. Now that is gone and the results are both obvious and welcome when dropping a gear. In reality this is really the only easily identifiable change noticed while riding with the Dura-Ace RD-R9150 Di2 Rear Derailleur. This is due to the fact that the shifting of it's predecessors has been fantastic, with impressive accuracy and operation at all times. Both SynchroShift and Instant Release come from XTR M9050 system, as does the new configuration of the body to the low-profile Shadow RD design. The final major change is that the short cage SS rear derailleur is now capable of handling an 11-30T max cassette, up from the 28T of the 9050 version. Shimano didn't stop the evolution there, with consideration to a few frame manufacturers (and thinking forward to more) that offer a direct mount system for the rear derailleur. The RD-R9150 offers that flexibility in a first for road bike use. At 204 grams, with sealed electronics and servo motor, you get premium shifting performance, high-end materials, supremely integrated engineering, and impeccable shifting from Dura-Ace Di2.
