Pain in lower abdomen after cycling with drop bars

[SkipdiverJohn]

After all that calculation the saddle certainly ought to be in the right ball park!

Sounds complicated but is very simple:- For example my inside leg is about 33 1/2".
Using Lemond (saddle height = 0.882 x inside leg + crank length) works out to 36 1/4".
Using Richards (saddle height = 1.09 x inside leg) works out to 36 1/2".

Actual saddle heights measured from own bikes based on trial & error comfort tweaking:-
Apollo MTB - 36 1/2"
Gemini hybrid - 36 3/8"
Pioneer hybrid - 36 1/2"

Both formulae seem pretty reliable to me!
