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: 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 Orbea Avant geometry shows systematic stack discrepancies across all seven sizes, ranging from 3.2mm to 3.9mm, indicating a data inaccuracy in either the published stack values or the published head tube length specification. Reach reconciles within ±1mm engineering tolerance across the entire size run. Wheelbase shows minor discrepancies on sizes 47 and 51 (2.3mm and 2.2mm respectively), while sizes 49, 53, 55, 57, and 60 reconcile within tolerance. Trail reconciles within ±1mm engineering tolerance across all sizes.
