Brommers-
Makes sense though, in that it is adjusted for the final position of the rider once the stem is fitted. I have a spreadsheet somewhere across bikes i have owned that adjust stack and reach taking into account spacers, stem length and angle.

Yes, took me some time get the 3d model right as well, but I don't mind now.

It’s actually stack+ and reach+
As that’s ultimately the contact point for your hands it seemed logical somehow to use it in the drawing. But sure, it’s more of a bike fit measurement than one used for frame building.

The guy I am building the bike for has done all his geometry drawing himself. Makes it pretty easy to work with.
