The 550 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.

How I read the maker's table
see bianchi-specialissima-2027.json for the new model, whose table differs only in the 500 / 530 reach cells (387 / 386 here). Front centre and fork offset published; trail not. Standover and trail are not published (null). Bianchi prints decimals with a comma on some pages (74,5) and sizes as three digits (470 = 47 cm); labels are kept as printed. Model year is not printed on the page (null); the drawing file names carry "W-2027" on the current Oltre and Specialissima.
