Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.| Size | Stack (mm) | Reach (mm) | Head angle (deg) | Seat angle (deg) | Head tube (mm) | Chainstay (mm) | Wheelbase (mm) | Standover (mm) |
|---|---|---|---|---|---|---|---|---|

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.Generic stem and barAssumedNo bar is listed for this frame.
In the maker's words
Kept whole, as I read it off argon18.com.Krypton Pro frameset with Argon 18's integrated cockpit on complete builds: the build page prints stock stem lengths XXS 70, XS 80, S 90, M 100, L 110, XL 110 mm and bar widths 40/40/42/44/44/44 cm c/c (not stored as stock fields because the geometry grid itself does not carry them and they vary by build).

How I read the maker's table
the Krypton (non-Pro) page prints the identical grid (argon-18-krypton.json). Fork rake, fork length and trail are not printed on this grid (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).
