Hi Luca,
Very interesting post for tall people.
"because I want as much height as possible together with some extra top-tube length"
>>> any idea how much that is?
With all your calculations, you probably also know the distance from the ground to the handlebar?
I thought S-type with risers was the way to go, but maybe P-type with M-bar is a better idea. Especially if they can do it in the factory. Any difference in top-tube length between the P-stem and the S-stem?
