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 |
|---|---|---|---|---|---|---|---|---|
| 470 (47 cm) | 493.5 | 362.8 | 69.5 | 73.5 | 100 | 415 | 978.7 | |

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 530 (53 cm) 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.

Cockpit and seatpost, in the maker's words · 139 words
NOT published. The maker's page (HongFu Sports Equipment / Shenzhen Hongfu Sports Goods Co., Ltd) describes the frame only: 'NEW DISC BRAKE AERO ROAD FRAME FM169-F, Item HF-FM169-F, 2022 AERO disc brake road frame new design, Material Toray T800, Available sizes 47/50/53/56/58cm, BB BB86/BSA, Maximum tire 700*28C, Rear axle 142*12mm, Front axle 100*12mm, Brake: Fork 140/160MM mount, Frame 140/160mm'. Title calls it 'Full internal cabel routing disc brake road frame' but no handlebar, stem, headset, spacer or top-cap details are given, and whether a bar/stem is included is not stated (integrated_cockpit left null). Seatpost: the geometry drawing shows a proprietary aero-profile seatpost with a wedge clamp at the top tube / seat tube junction; seatpost length and offset are NOT published. Fork: full-carbon disc fork, length (I in the drawing) 368 mm axle-to-crown, offset (K) 45 mm, all sizes.

How I read the maker's table
table upscaled 3x to read). STACK DATUM: D is drawn from the BB centre vertically to the horizontal through the top of the head tube, C horizontally from the BB vertical to the head tube top centre - the usual stack/reach convention. H = front centre was confirmed rather than assumed: sqrt(H^2 - drop^2) + sqrt(RC^2 - drop^2) reproduces the published wheelbase to within 0.1 mm on every size, and reach + stack / tan(STA) reproduces B to within 0.1 mm on every size, so the table is internally consistent as read. Size names: the table uses 470/500/530/560/580 and the text says 47/50/53/56/58cm; the size_label carries both. Standover and trail are NOT published (left null; do not import derived values). Weight per size (frame, published): 47cm 1069+-40 g, 50cm 1072+-40 g, 53cm 1087+-40 g, 56cm 1107+-40 g, 58cm 1127+-40 g. Model year: the description opens '2022 AERO disc brake road frame new design' and the page was published 2022-04-13; the og:url on the page points at /products/roadbike/19.html and the article link at /case/19.html, all the same record. The road bike category listing on the maker's site (https://www.hongfu-bikes.com/products/roadbike/) has only this one FM169-F entry. No aggregator was consulted.
