Geometry, every size, from the maker's table
The tinted row is the size drawn beside it. Press a size to draw it.| Size | Stack (mm) | Reach (mm) | Head angle (deg) | Seat angle (deg) | Head tube (mm) | Chainstay (mm) | Wheelbase (mm) | Standover (mm) |

The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The ML 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
front centre published. Trek's gravel race platform. Model year 2025 from the asset id. 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. Cross-checked SKUs: 58668 (Checkmate SLR 7 AXS) not fetched.
