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
Fork rake, fork length and trail not printed (null). UNITS: Argon 18 prints lengths in centimetres to one decimal (some pages with a decimal comma) and angles in degrees; every length was multiplied by 10 to give millimetres. ARGON 3D SYSTEM: the frames take head tube extensions (0 / 15 / 25 / 35 mm depending on model); the page prints H2/H3 head tube lengths and the "Stack 3D (25mm)" / "Reach 3D (25mm)" rows for the extended settings - this file stores the 0 mm (bare) values and the extended stack/reach are in notes. Front centre not published (null). Argon prints fork rake and fork length under a "cm" unit label but sometimes as millimetres (e.g. "51.0" rake, "400.0" fork length): values of 20 or more were taken as millimetres, smaller ones as centimetres. Size labels XXS-XL with Argon's cm equivalents 44-46 / 47-50 / 51-53 / 54-56 / 57-59 / 60-62. Model year not printed (null).
