The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 52 / 520 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.

How I read the maker's table
TABLE LEGEND (drawing above the table, headed LCTT001): C-T = seat tube, centre to top (seat_tube_length); A = head tube length; Offset = fork offset, printed "45 deg" on every size (a maker typo for 45 mm: a fork offset is a length; recorded as 45); TT = top tube, horizontal; HT and ST = head and seat tube angles; BB = BB drop; RC = chainstay; WB = wheelbase; FC = front centre; Stack and Reach from the BB centre to the head tube top. B on the drawing is the fork length (not in the table). The right-hand block reads RD Inner, FD Inner, POST "Special 74-78 deg", H/T INSERT "FSA NO. 88", BB INSERT BB86. The 460 and 490 wheelbases are printed 950.3 and 951.7 (almost equal although the 490 is 20 mm longer in the top tube), as printed. SIZE LABELS: the image table heads its rows 460 / 490 / 520 / 540 / 560; 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.
