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 Cannondale Topstone Carbon's published geometry reconciles within ±1mm engineering tolerance across all six sizes for stack, reach, wheelbase, and front center. The engine refined the fork axle-to-crown length to 428.9mm via two-pass consensus to achieve this reconciliation. Trail values reconcile at 0.0mm by construction, as the engine accepts the manufacturer's published trail as authoritative and derives the implied tire (700 x 47c) that produces those values.
