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!
Compatibility warning: none of the 7970 series components will work with other generation Di2 components. The plug is different and simply won't fit.
These DURA-ACE 7970 Time Trial Bar-end shifters come with electric wires attached. You plug them into the ST-7970 shift levers.
If you're looking for an aerobar alternative that will work with current generation Di2, have a look at either the two-button SW-R671 or the DURA-ACE SW-R9160 shifting switches.
