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.
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
Time trial frame. 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 are in the feed but not in the schema. Front centre is not in this feed (null).
