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: yellow. 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 Salsa Warbird geometry shows systematic stack discrepancies across all five sizes, with published values consistently 2.0–3.9mm below the engine's forward-model calculations. Reach reconciles within ±1mm engineering tolerance across all sizes. Wheelbase reconciles within tolerance on four sizes (52.5cm–57.5cm); the 49cm size shows a 4.2mm data inaccuracy in the published value. The seat tube angle progression shows unusually large single-step changes of 1.0° between adjacent sizes (49cm→52.5cm and 52.5cm→54.5cm), which may indicate transcription anomalies — verification of the affected sizes is recommended.
