I installed SW-7972 Dura-Ace satellite shifters on my 6870 commuter bike by doing some cutting and soldering, as well as some creative wiring.
Remote Satellite Sprint Shifter
Compatibility warning: none of the 7970 series components will work with other generation Di2 components. The plug is different and simply won't fit.
The SW-7972 Satellite shifting switch is the 7970-series sprinter satellite switch. It allows for quick and easy shifting while in the drops.
