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 Niner ORE 9 RDO gravel bike demonstrates strong internal geometric consistency across all six sizes (47cm–62cm). Stack, reach, wheelbase, and front center all reconcile within ±1mm engineering tolerance. The RideDNA Geometry Engine reconciliation checks confirm internal self-consistency of the published specification, with all back-calculated dimensions falling within ±1mm of their published counterparts. One data quality flag was identified: seat tube angle shows an unusually large single-step change of 1.0° between sizes 53cm and 56cm (74°→73°), which warrants verification — the root cause cannot be determined from the published geometry data alone.
