Cockpit and seatpost, in the maker's words · 83 words
SOLD AS A FRAMESET by an OEM factory ("I want to inquire"); no bar, stem or seatpost specification on the page, so stock_stem_length and stock_bar_width are null.

How I read the maker's table
The product page names the frame "2018 Disc brake Road Frame, Item: HF-FM088" (hence model_year 2018, the year the maker prints) and lists "Available sizes: 45/48/50/52/54/56/58cm"; the drawing's table uses 450/480/500/520/540/560/580, so labels here are "<table size> (<cm>)", matching the other Hongfu files. TABLE LEGEND (from the labelled drawing): S = seat tube, BB centre along the tube to the top tube junction as drawn; TT = top tube, horizontal (top_tube_effective); SA = seat angle; HT = head tube; HA = head angle; F = fork length 368 every size (not a schema field); OT = fork offset 45; WB = wheelbase; FC = front centre, BB centre to front axle; RC = chainstay 410; G = BB drop (72 on 450-500, 69 on 520-580); Reach and Stack drawn from the BB centre to the head tube top. The size order does not keep reach rising: 520 prints reach 385.6 and 540 prints 384 (with stack 522 then 543); both close their own top tube within 1 mm, so this is the maker's design (the 540 is a taller, steeper front), not a misread. NOT PUBLISHED: standover, trail (null). Bike Insights lists FM088 2021 with sizes 45-58 citing an AliExpress listing (see cross_check); its numbers differ slightly from the maker's drawing. No Panda Podium, Geometry Geeks or 99 Spokes request was made.
