Geometry, every size, from the maker's table

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

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 Trinity before the MY2027 Trinity Advanced SL (giant-trinity-2027.json, 32 of 48 cells differ). Four sizes XS, S, M, L in the table; the spec Sizes line reads "XS, S, M". Seat angle 77, head angle 73, rake 40 and trail 61 on every size. Giant does not say whether the seat angle is effective or actual (null), does not publish front centre (null) and does not state the stack datum (null). Stock tyre "Giant Gavia Course AC 1, tubeless, 700x25, folding".
