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 MD 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. A dashed tube is a number the maker left out (est.).

How I read the maker's table
The SLR 8.9 Carbon page (C7 carbon, https://www.boardmanbikes.com/gb_en/products/2422-slr-8.9-carbon.html, checked 2026-10-20) prints the same geometry cell for cell, so one file covers the current SLR carbon range. This is a different table from the 2021 SLR 8.9 Disc (boardman-slr-2021.json: SM to XL, SM stack 546) and the 2021 SLR 9.6 Disc (boardman-slr-9-disc-2021.json). The "Sizes & Fit" panel (div rows in the page markup, not a <table>) prints: Standard Range Size, Recommended Height, Recommended Inseam, Stack, Reach, ST Seat Tube, TT Top Tube, HA Head Angle, SA Seat Angle, CS Chain Stay, BB Bottom Bracket Drop, Crank Length, Stem Length, Handlebar Width. Degree signs stripped by the parser. Trail and standover are not printed (null); stack datum not stated (null). This panel prints NO head tube, fork offset or wheelbase (null). Tyres 700 x 30mm (Goodyear Eagle F1 R on the 9.8). Model year: not printed (null).
