The Shimano EW-RS910 is a Junction-A box for Internal Bar or Frame mounts, connecting the various parts of the Shimano Di2 drivetrain. Mounting simply and easily to either a bar end or dedicated ports that some frame manufacturers are including in the frames, the EW-RS910 makes an easily accessible charging port and a clean aesthetic that makes any bike look like a streamlined race machine.

Shimano Junction A complete Di2

Shimano EW-RS910 Junction A for Internal Bar/Frame Mount; Its a must have for the Di2 system. It fits in the handle bar or specific placement on bike (down tube). Engineering, I wish it was more user ergonomic; the button is 'stiff', and the door opens downward to 'charge' the proprietary Di2 system battery....however, you still need this to complete the system. Allows user to plug into PC update components, and charge battery.

Cockpit is seamless

Get rid of the under the stem blemish from the older junction and tighten up the aesthetics !

Can modify most aluminum and carbon bars to accommodate the wiring easily .

Super way to clean up your bike

I wanted to clean up my front end and this did the trick. It should become the standard approach - more aero for sure.

It just works. I also upgraded to bluetooth at the same time...
