Aside from the obvious puritanical beauty of an "analogue" classical bike... what bull... shifting with mechanical STI levers is substantially more strenuous on your fingers than Di2... and it's not mere milliseconds... especially with multiple consecutive shifts. When I built a Di2 flatbar for city use - I eventually had to ditch my old mechanical Trek Madone for a Di2 roadbike... it was simply too big a QOL improvement to pass up.

I totally agree! I have that on both my Di2 bikes... even my Dura-Ace spec S-Works. I'm not always sure where the front-derailleur currently is otherwise x) ...and the battery indicator entirely removes any charging concerns/issues.
