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 Bianchi Infinito geometry reconciles within ±1mm engineering tolerance across all seven sizes for stack, reach, wheelbase, and front center. The forward-model calculations, anchored to the published Effective Top Tube length, align closely with the manufacturer's published specifications. The RideDNA Geometry Engine reconciliation checks reveal a systematic stack inflation pattern: published stack values appear approximately 1.1mm higher than what the other published geometry parameters imply, affecting three of the seven sizes at the yellow threshold.
