Published geometry by size

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.

Audit context

Overall consistency: green. 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 Madone SLR published geometry reconciles within ±1mm engineering tolerance across all six sizes for stack, reach, wheelbase, front center, and trail. The manufacturer's specification demonstrates internal geometric consistency across the size run. One data quality flag warrants attention: size XS shows STA > HTA (73.8° vs 71.6°), opposite to the model-line dominant pattern (HTA > STA across the other five sizes) — this minority inversion may indicate an HTA↔STA data entry swap and a vision re-audit of that size is strongly recommended.
