Geometry, every size, from the maker's table

The tinted row is the size drawn beside it. Press a size to draw it.

The 55 drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm.

The maker's cockpit

No stock cockpit I can name, so every size is solved on a generic stem and bar unless you choose one on the sheet.
