How I read the maker's table
each frame has a half page with a spec list, a dimensioned drawing and a table. No product page for this frame is in lightcarbon.com's sitemap (fetched 22 Oct 2026), so the catalogue is the maker's own publication of it; model_year 2026 is the first year of the catalogue's "2026-2027". Columns as printed (the drawing's red labels say what each measures): SIZE; C-T seat tube length; TT "top tube length, horizontal" (top_tube_effective); REACH and STACK (drawn to the head tube top); WB; RC chainstay; FC front centre; BB DROP; BB HEIGHT (not in the schema); ST seat tube angle; HT head tube angle; STIL (a seat-mast insertion figure at the seat clamp, not in the schema); A head tube length; Standover Height; Offset (fork rake); FL "fork length, full" (not in the schema); TRAIL (maker-published, kept). LCG072-D, "Racing Gravel", "700C Aero Racing Gravel Carbon Frameset With Downtube Storage": Toray T700+T800+M60J; sizes S/M/L/XL; full internal cable routing; weight (+/-4%) 1100g/Size M UD matte; head tube "Straight 1 1/2 in head tube (upper 52mm lower 52mm)"; seat post "special shape (special clamp)"; stem 80/90/100/110/120/130mm and handlebar 380/400/420mm; BB T47*P1.0 (85.5mm); max tire "700C*50C & 650B*2.0"; rear TA 12*142mm; fork TA 12*100mm; flat mount 160/160mm; UDH. BB HEIGHT 284/284/284/287; STIL 120/140/160/180; FL 383; standover printed for a 700x50C tyre (tyre_width_mm 50). The XL's BB drop is 76 where the others print 79 (and its BB height 287 against 284, consistent).
