    Di2 Shifting Systems:
    Expanded Shimano Synchronized Shift capabilities debut for road

    First introduced in XTR Di2 M9050, Shimano’s innovative Synchro Shift is now available with DURA-ACE R9150/R9170. Available as a programmable Di2 option, Synchro Shift creates an intuitive experience on the bike through synchronized 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 minimize the gear step, thus preserving the rider’s rhythm.

    Shimano Synchronized Shift will be available for all previous 11-speed Di2 road component groups with the use of new Di2 firmware and accessories in November 2016.

    Di2 shifting performance for all braking solutions

    A true drivetrain system for the next generation race bike, DURA-ACE Di2 performance is now available for both mechanical rim brake and hydraulic disc brake configurations. Both Di2 Dual Control Lever options feature a refined hood shape with svelte shared ergonomics for more rider control in race conditions, regardless of braking choice.

    The ergonomically-enhanced Di2 shift levers now produce a more defined shift click for a more intuitive feel and quicker shifting operation and expanded E-Tube customization allows every switch the option to independently turn on or off multi-shift. The versatile SW-R9150 Remote Satellite Shifter expands customization possibilities further.
