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

How I read the maker's table
the page "CS-GR01 Gravel bike frameset" (category Gravel/CX Frame, posted "Time:2024-04-30"; no model year printed, model_year null) is still live and is not on the .cc store. Its geometry is one image (uploaded 2024-05-09). Columns as printed, XS/S/M/L/XL/XXL: A "BB center to top of seattube"; B "Effective top tube horizonta(l)" (top_tube_effective); C "BB offset" -72 every size (recorded as bb_drop 72, the drop printed with a minus sign); D chainstay length 425; E seat angle; F head angle; G front center; H head tube length; I fork offset 55; J reach; K stack; WB; FL fork length 395 (not in the schema). No trail or standover printed. PROBABLE SLIP, kept as printed: the XXL stack 636 equals the XXL front centre 636 in the same row and does not close its own top tube (398 + 636 / tan 73 = 592.4 against the printed 588; a stack of 622 would close, and the step from the XL would then be 20 mm, matching the 20 mm head tube step); every other size closes within 0.5 mm. Spec text: carbon fibre T800, sizes XS/S/M/L/XL/XXL, "Weight: Frame, 1234+/-30g Fork, 450+/-15g Seat post, 184+/-10g" (no size named), finish UD matte or glossy or custom paint, "BB: T47-86.5-24mm", UDH hanger, front 100*12 and rear 142*12, max tire 700*50C. Bike Insights files the CS-GR01 with eleven size rows (XS, S, S2, M, M2 and so on).
