Geometry, every size, from the maker's table

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The 56cm 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.
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.
In the maker's words
Kept whole, as I read it off api.trekbikes.com.Complete bikes ship with Trek's two-piece stem and bar (RCS stem or Bontrager Elite / Pro bar, sizes per build, not per frame); the frameset carries no bar.
Cockpit and seatpost, in the maker's words · 49 words
Complete bikes ship with Trek's two-piece stem and bar (RCS stem or Bontrager Elite / Pro bar, sizes per build, not per frame); the frameset carries no bar. Spacer heights, top-cover height and maximum spacer stack are not in the sizing feed. stock_stem_length null unless the feed carries geometryLengthStem.

How I read the maker's table
These are NOT the current (2021-on, Gen 3) Emonda SL/SLR numbers: the Gen 3 feeds (32688 Emonda SL Disc Frame Set and 35487 Emonda SLR 7) print e.g. size 60 stack 601 / reach 399, where this feed prints 615 / 395, and the Gen 3 sizes stop at 62; this is the earlier H2-fit Emonda SL frame set that Trek still serves through the feed (size run 44-64 matches the 2017-2020 Emonda SL). Recorded as a previous-generation table with the code in the model name; model year not stated (null). Front centre not published (null). The current Gen 3 Emonda SL/SLR table could not be collected: its feeds now list only the sizes still in stock (47, 60, 62), so it is reported as incomplete rather than written. UNITS: Trek publishes the table in centimetres to one decimal and angles in degrees; every length was multiplied by 10 to give millimetres, no rounding was needed. Column mapping from Trek's geometryDataHeaders: geometrySeattube -> seat_tube_length, geometryAngleSeattube -> seat_tube_angle, geometryLengthHeadtube -> head_tube_length, geometryAngleHead -> head_tube_angle, geometryEffToptube -> top_tube_effective, geometryBBDrop -> bb_drop, geometryLengthChainstay -> chainstay, geometryOffset -> fork_offset, geometryTrail -> trail, geometryWheelbase -> wheelbase, geometryStandover -> standover, geometryFrameReach -> reach, geometryFrameStack -> stack, geometryFrontCenter -> front_centre (where present). Stack and reach are Trek's frame stack/reach to the head tube top. The feed lists only the sizes of the chosen SKU, so the SKU with the fullest size run was used; where Trek publishes saddle-rail height ranges (short and tall seatposts) they are in the feed but not in the schema.
