The 53 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. A dashed tube is a number the maker left out (est.).

How I read the maker's table
no wheelbase, BB drop or standover rows on this page (null); three front-centre cells printed with a degree sign instead of mm (589.1, 596.1, 593.5) and taken as mm. Values printed with a decimal comma on some pages (converted); several cells carry a stray degree sign instead of mm (e.g. "589.1°" for a front centre) - taken as mm. Fork offset and trail are not published (null). Model year not printed (null).
