...Nevertheless, a 13 cm stem means a wrong fitted bike. The perfect fit is considered with a 10 cm stem. And that´s all. Your saddle handlebar drop is huge, because your frameset size is wrong, and in fact it can´t be right with "standard framesets"...
I am curious as to how you come to this conclusion.
Why is 100mm stem perfect?
This is the point where I tend to disagree with you Beat.
Professionals are not the best place to look, however, I am sure you will find quite a few 130mm stems running around.
I believe the best size frame, stem, drop, set back etc is the one where the person is comfortable, addresses postural issues (if any), produces the most power, facilitates good handling and optimises aerodynamics (if applicable). If this necessitates a 150mm stem and a 50cm frame for someone who is 190 cms tall, then so be it. This may result in a setup and position that is wrong by conventional means.
Unless you have some solid data or studies to show me otherwise then I will maintain my belief that positioning requires a holistic outlook not a formulae.
That being said, if I were fitting someone to a bike, I would use something like your spreadsheet to start with. However I would not be concerned should the end result be far, far from this.
13 cm stem means a bad fitted bike, that´s all. Well at least the bike frameset is not made for you, that´s what i ment.
Nevertheless, i think you must measure your body better, Superfast has quite normal arms, and not very short.
My spreadsheet is a guide, i have another version considering "back flexibility", but again is not worthy, you can find your best fit according to the sheet, and just "give your touch" to finish. Same can be told for Ant, his body measures must be reviewed.
The one who has neck pain, perhaps you must try another handlebar, yours seems to be wider than you need.
