Technology

Synchro Shift
First introduced in XTR Di2 M9050, Shimano’s innovative Synchro Shift is now available with Dura-Ace R9150. Available as a programmable Di2 option, Synchro Shift creates an intuitive experience on the bike through Synchronised front and rear shifting that can be custom programmed by riders.
In addition to traditional “Full” Synchro Shift, riders can optionally select “Semi” Synchro Shift. This intuitive new mode automatically reacts when the rider shifts from one chainring to another, automatically shifting the rear derailleur to minimise the gear step, thus preserving the rider’s rhythm.
