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)not published |
|---|---|---|---|---|---|---|---|---|
| 48 / 480 | 497.5 | 382.6 | 72.5 | 75 | 71.5 | 395 | 945.7 | |

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 54 / 540 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. A dashed tube is a number the maker left out (est.).
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.

The geometry image's own block gives "HB-Size 420" and "Stem-Size 100" for every size (integrated base bar and stem); recorded as stock_bar_width and stock_stem_length. Seatpost "Special 74-78 deg" (an aero post adjustable over that effective seat angle range).

How I read the maker's table
TABLE LEGEND (drawing above the table): A = head tube length (drawn along the head tube top); offset = fork offset; TT = top tube, drawn horizontal (top_tube_effective); HT = head tube angle and ST = seat tube angle (arcs on the drawing); BB = the BB drop drawn as G; RC = chainstay; WB = wheelbase; FC = front centre; STACK and REACH from the BB centre to the head tube top. The drawing also prints the fork length 370, wheel radius R340 and tyre 700C*25C; the table prints no seat tube length. The table's right-hand block reads RD Inner, FD Inner, POST "Special 74-78 deg", H/T INSERT "FSA NO.8B", BB INSERT "BB386 ID:46", Brake "Special", HB-Size 420, Stem-Size 100. TOP TUBE: reach + stack / tan(75) is 1-5 mm longer than the printed top tube on every size; the seat angle check will show it and nothing was changed. SIZE LABELS: the image table heads its rows 480 / 510 / 540 / 570; the page spec table lists the cm sizes; size_label carries both as "cm / mm". NOT PUBLISHED: standover, trail (null). MODEL YEAR: not printed (image uploaded 2023-09-07); model_year null. No Panda Podium, Geometry Geeks or 99 Spokes request was made.
