There is another attempt to ridicule things Frank. Lets do the same.
If you are scared by simple hardware and software that poll 4 simple
switches and when it detects that a switch is actuated it sends a
predetermined amount of pulses and a direction signal to the right
stepper motor maybe you should consider a bike with a wheel you can
flip to get the other gear like in the very old days. Why risk a
failure of a cable or a complex mechanical device such as a
derailleur with multiple pivots and a springs that can fail. Then of
course you only have two gears and you have to stop and get off the
bike first but hey you are not racing so it shouldn't matter. Your
toaster, oven and dishwasher is more complicated than Di2.

Oooh! OOOH! Sir! SIR!
