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). LCR020-D, "Super Aero Race", "700C Super Aero Racing Road Disc Brake Carbon Frameset": Toray T800+T1100+M40J; sizes "47/49/52/54/56/58/61cm" (the table labels them 470 to 610, kept); weight (+/-4%) 1000g/54cm UD matte; head tube "integrated 52mm/52mm"; seat post "special shape (special clamp)"; stem 80/90/100/110/120/130mm and handlebar 360/380/400/420mm (LightCarbon's own cockpit; no model named); BB T47*P1.0 (85.5mm); dropout TA 12*142mm; fork TA 12*100mm; flat mount 140/160mm; max tire 700C*35C; "Light UDH". BB HEIGHT 280 every size; STIL 130/150/170/190/200/210/220; FL 370; standover printed for a 700x35C tyre (tyre_width_mm 35). Bike Insights files this frame twice (LCR020-D 2026 and 2026 V4).
