Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The L/520mm 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
reach I is horizontal from the BB vertical to the same head tube top point; head tube length J is measured along the head tube; top tube H is labelled "Top Tube Lenght Horizontal" (effective, horizontal); seat tube length F is BB centre to the top of the seat tube along the tube; seat tube angle B is drawn at the BB between the horizontal and the seat tube line, and the table labels it only "Seat Tube Angle B(deg)" - effective vs actual is not stated (the seat tube is straight, so the two should coincide); head tube angle A; chainstay C; BB drop D; wheelbase E; fork length full K (axle to crown) 378 mm all sizes; fork rake/offset L 43 mm all sizes; front centre M is PUBLISHED (582 / 589 / 600.4 / 619.6). Standover and trail are NOT published (left null). Sizes are named "S/455mm; M/485mm; L/520mm; XL/560mm" - the number is the seat tube length in mm; four sizes only. Table labels reproduced with the maker's spelling ("Lenght"). Rider height guide ("Size Recommend"): S 155-168 cm, M 165-178, L 175-188, XL 185-196. Frame-only weights (+/-20 g): S 937 g, M 957 g, L 999 g, XL 1049 g; components (+/-2 g): rear thru-axle 37 g, front thru-axle 30 g, fork 429 g, seatpost 137 g, integrated drop bar 90x400 312 g, hanger 30 g. Frame facts: T800+T1000 (reinforced) carbon, full internal cable routing, T47 bottom bracket (included), max tyre 700x32C, thru axles 12x100 front / 12x142 rear, disc rotors 140/160 mm, crankset compatibility 34/50T or 39/52T, rear derailleur hanger HX9 (UDH not mentioned), 2-year warranty, seven paint options, SKU X9AS455S, USD 799 (was 1059) on 2026-08-29. MODEL YEAR: not stated anywhere on the page (JSON-LD has no date; footer copyright 2020-2025). The copy calls this an "Upgrade ... Lighter Than Previous Models", so it is the revised X9; the page's detail images were uploaded 2026-04 to 2026-08 (timestamps in the image file names) while the menu thumbnail dates from 2023-04, so an older X9 with different numbers may exist - treat this file as the current (2026) listing, model_year left null. stock_stem_length 90 and stock_bar_width 400 are the size-independent "90*400mm" bar in the frameset weight table, not a per-size spec.
