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) |
|---|---|---|---|---|---|---|---|---|
| 49 / 490 | 542.6 | 374.1 | 71 | 73.5 | 120 | 430 | 1008.9 | 776.4 |
| 52 / 520 | 563.4 | 377.5 | 71.5 | 73 | 140 | 430 | 1014.5 | 793.4 |

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 55 / 550 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.

How I read the maker's table
the product page "LightCarbon New Gravel Frameset With Integrated Handlebar" (item no. LCG071-PRO) publishes the geometry as a real HTML table with named rows, parsed from the raw HTML. The same table appears on: p171 (item no. LCG071S-PRO, https://www.lightcarbon.com/new-carbon-gravel-frameset-with-integrated-stem-system_p171.html, 203827 bytes): identical geometry rows; p254 (item no. LCG074-D, https://www.lightcarbon.com/lightcarbon-gravel-frameset-micro-suspension-pivot-design-with-integrated-handlebar_p254.html, 208388 bytes): identical geometry rows; p255 (item no. LCG074S-D, https://www.lightcarbon.com/lightcarbon-gravel-frameset-micro-suspension-pivot-design-with-stem_p255.html, 205988 bytes): identical geometry rows. ROW MAPPING: REACH, STACK, WHEELBASE, CHAINSTAY LENGTH, FRONT CENTER, BB DROP, SEAT TUBE ANGLE, HEAD TUBE ANGLE, SEAT TUBE LENGTH, HEAD TUBE LENGTH, FORK RAKE/OFFSET and TRAIL map one to one; "TOP TUBE LENGTH, HORIZONTAL" is top_tube_effective; "BIKE STANDOVER HEIGHT(700C*53C)" is standover (the tyre the maker measured it with is in the row name). Rows not in the schema, kept here: Seatpost Insert Length 180mm / 220mm / 250mm / 270mm; Bb Height 285mm / 285mm / 285mm / 285mm; Bike Standover Height(650B*2.1") 766.4mm / 783.4mm / 823.4mm / 853.9mm; Fork Length, Full 397mm / 397mm / 397mm / 397mm. Body-height bands are printed per size "for reference only". STACK DATUM: not stated; recorded as the usual head tube top. SIZE LABELS: the geometry table heads its columns 490 / 520 / 550 / 580 and the spec table lists "49, 52, 55, 58 (cm)"; size_label carries both as "cm / mm". The maker prints the SAME geometry table, cell for cell, on four pages: LCG071-PRO (gravel frameset with integrated handlebar, down tube storage), LCG071S-PRO (its integrated-stem version), LCG074-D ("micro suspension pivot design", integrated handlebar) and LCG074S-D (its stem version); they are recorded as one file because there is one table, and both model names are kept. HBR08 integrated gravel handlebar 380/400/420/440 mm with stems 90-120 mm; straight 1 1/2 in head tube (52/52 mm bearings). standover is the 700C x 53C row; the maker also prints a 650B x 2.1 in standover row (766.4 / 783.4 / 823.4 / 853.9 mm), not a schema field. MODEL YEAR: not printed; model_year null. No Panda Podium, Geometry Geeks or 99 Spokes request was made.
