With the launch of the Dura-Ace 9100 comes new firmware offering road riders Synchronized Shifting options between front and rear derailleurs.
This technology has now been made available to Ultegra 6800-series and Dura-Ace 9000-series riders who have the latest Di2 battery.
The new battery contains a memory chip that can handle the processing power required to deal with the multiple shift patterns and customizations that Synchronized Shifting brings, offering riders the choice to suit their gear positioning to their personal riding style.
To access the new features, users must first ensure that they have the new BT-DN110 battery – the only battery that allows users to take advantage of automated front shifts or automated rear 'correction shifts'.
If riders currently use Di2 with compatible front or rear derailleurs, they can download the latest E-TUBE firmware either by a cable connection to a PC, or via Bluetooth from a tablet or smart phone to their components.
