Di2 Compatibility - mix Ultegra, DURA-ACE, XTR, XT and GRX components
Did you know that you can mix Di2 components from different series and categories? Mixing derailleurs is not recommended, but anything else is fair game!
TT / Bar-end shifting switches
DURA-ACE SW-R9160
The SW-R9160 remote TT/Triathlon shifter allows for shifting when using TT aero bars. It is mounted at the end of the aero bar/extension.
Synchronized Shift
If you're using a front derailleur on your bike it's worth knowing that these buttons only have one button each. This means that you'll have to use Synchronized Shift to operate the front derailleur. Don't like the sound of that? Then consider installing the SW-R671 2-button switches instead.

These shifters are 12-speed compatible, if you update them to firmware version 3.3.0 or newer.
In order to update these shifters, either connect them to the SM-PCE02 or SM-PCE1 on their own, or connect them to an 11-speed Di2 bike and use the SM-BCR2 charger to run the firmware update.
No wireless
These shifters have to be connected to the BT-DN300 battery by wire. They will not function if there isn't a wired connection between them and the battery.
You could plug them into one of the wireless shift levers, but they won't work unless you then connect the shift levers to the battery by wire.
