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.

Cockpit and seatpost, in the maker's words · 48 words
Trek's sizing feed carries no bar or stem rows for the Madone Gen 7, and no Trek cockpit page was read for this file (integrated_cockpit null: not read, not assumed). Bike Insights cites the Madone SLR 9 Gen 7 product page, https://www.trekbikes.com/us/en_US/bikes/road-bikes/performance-road-bikes/madone/madone-slr/madone-slr-9-gen-7/p/37419/, for the bar collector to read.

How I read the maker's table
The Madone SL 7 Gen 7 feed (code 41467; Trek's US code 5298633 resolves to it) prints identical rows, so this is the Gen 7 platform table for SL and SLR, the Madone before the Gen 8 in trek.json and trek-madone-sl-gen-8.json. Every frame number equals the Emonda Gen 3 feed (trek-emonda-gen-3.json) and the Madone Gen 6 feed (trek-madone-gen-6.json) except standover, which is 15 to 27 mm higher here (47 cm 707 against 692, 62 cm 853 against 829). Size labels are printed "47cm" with no space. UNITS: Trek publishes the table in centimetres to one decimal and angles in degrees; every length was multiplied by 10 to give millimetres (Decimal arithmetic, exact, no rounding). 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 (Trek's frame stack and reach, so stack_datum head tube top). Saddle rail height ranges for the short and tall seatposts (geometrySaddleRailHeightMinShort/MaxShort/MinTall/MaxTall) are in the feed but not in the schema. Front centre is not in this feed (null).
