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 Orbea Orca's published geometry reconciles with the RideDNA engine's forward-model calculations within ±1mm engineering tolerance across all seven sizes. Stack, reach, wheelbase, and trail all show deltas ≤0.3mm, confirming internal consistency of the manufacturer's published specification. The model uses intentionally different fork offsets across the size run (48mm for sizes 47–51, 43mm for sizes 53–60) to maintain consistent handling characteristics across the head tube angle range.
