Shimano Dura-Ace R9160 Di2 Bar End Shifters

These shifters are designed for use with Shimano's E-Tube Di2 electronic shifting systems. While they are compatible with most modern Di2 setups, you should ensure your current junction box and derailleur firmware support the specific configuration you intend to build.

The single-button design relies on Shimano's Synchro Shift technology. Because the system automatically manages front derailleur shifts based on your rear gear selection, a single button is all you need to move through your cassette, simplifying your cockpit and reducing the chance of accidental shifts.

Yes. Using the Shimano E-Tube Project app on your mobile device or desktop, you can customize the button assignment and shifting behavior to suit your personal preferences and racing style.

Installation is straightforward, but you will need standard hex keys to secure the shifters into the ends of your aerobars. Ensure your bars have the correct internal diameter to accommodate the mounting hardware before beginning.

Synchro Shift is a feature you can toggle on or off. You can set the system to full Synchro Shift, semi-automatic, or manual mode, giving you complete control over how your drivetrain reacts to your inputs.
