A size-by-size geometry profile with manufacturer provenance and RideDNA consistency-audit context. Use the complete table to compare fit and handling before opening the interactive tools.
Source: Manufacturer geometry source
Provenance: published is present in the manufacturer data; derived is calculated by RideDNA; manual is a staff-entered reference rather than a manufacturer-chart value. “Not published” means the manufacturer did not provide a value for that size.

Overall consistency: red. This context is shown alongside the table so a rider can distinguish a complete published specification from a value that RideDNA had to derive or could not independently verify.
The Trek Domane SLR Gen 5 geometry exhibits a systematic stack mispublishing pattern on sizes XS, S, and M, where published stack values are deflated by 8.3–9.5mm relative to what the other published geometry parameters imply. Sizes ML, L, and XL reconcile within ±1mm engineering tolerance across all checks. Reach shows 2.8–6.0mm data inaccuracies on sizes XS–M and 2.8–3.2mm data inaccuracies on sizes ML–XL, while wheelbase and front center show 2.8–3.8mm data inaccuracies across all sizes. The RideDNA Geometry Engine reconciliation checks confirm that the published stack values on the smaller three sizes are internally inconsistent with the published head tube length and fork A2C specification.
