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 BMC URS geometry reconciles within ±1mm engineering tolerance across all five checks (stack, reach, wheelbase, front center, trail) on all five sizes. The manufacturer's published specification is internally consistent and aligns with the RideDNA engine's forward-model calculations. This model demonstrates high geometric data integrity.
