Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The M 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.

How I read the maker's table
Five sizes XS to XL. Not the Terra C chart (orro-terra-c), though stack, reach, head tubes and wheelbases are the same: top tubes 532/584/612 against 529/581/604 on S, L and XL, seat angles 74.5/73.0/72.3 against 74.9/73.3/72.6, L chainstay 422 against 422.5. Bike Insights' Terra X 2023 entry prints the Terra C numbers instead. Not printed: fork offset, standover, front centre, trail, stem and bar (null); stack datum not stated (null). Model year: the listing on the fetch date, so model_year null.
