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 M 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.).
The maker's cockpit
No stock cockpit I can name, so every size is solved on a generic stem and bar unless you choose one on the sheet.Generic stem and barAssumedNo bar is listed for this frame.

How I read the maker's table
Column mapping: Stack; Reach; Ss -> head_tube_angle; Sc -> seat_tube_angle; A (BB centre to front axle) -> front_centre; C -> chainstay; Wheelbase; Hs -> head_tube_length; Rake -> fork_offset; "Fork Length" not in the schema; BB drop -> bb_drop. Size labels as printed (S, M, L). DRAWING (read only for its letters and datums, not stored): Stack and Reach are drawn from the BB centre to the top of the head tube (no headset cover named, so stack_datum is null); O is drawn horizontal from the head tube top to the seat tube line; the size is drawn along the seat tube from the BB centre to its top. Not published, so null: standover, trail, seat tube length, top tube, stock stem, stock bar. THE PAGE AGAINST THE CHART: the page's own size tabs print 30 of these cells; every one agrees with the chart. A track frame (dual crown fork, 65 mm front hub). Fork length 372 mm. Model year is not printed (null).
