Technology

Synchro Shift
Initially introduced with the XTR Di2 M9050 group, the innovative Synchro Shift technology is now available on the Dura Ace R9150. It is a Di2 programmable function that creates an intuitive experience on the bike through the synchronization of the front derailleur and rear gearbox, which can be programmed directly by the user. In addition to the "Full Synchro" function, a "Semi Synchro" function can also be used: this is a new mode that automatically reacts when the rider switches from one crown to another, also changing the position of the rear derailleur to reduce the gear jump, thus preserving the right pace.

Not compatible with Shimano D-Fly SM-EWW01.

Not compatible with SM-BTR2-1 Shimano battery.
