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.

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
The triathlon Shiv (not UCI legal), a different frame and table from the Shiv TT Disc (specialized-shiv-tt-2020.json: 40 of 48 cells differ). Four sizes XS, S, M, L; the seat angle is printed 77 on every size. Bike Insights holds the same table as "S-work shiv Disc 2022". Values printed with mm and degree suffixes, stripped by script.
