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.

Geometry reconciliation applies a 6mm integrated headset top cap correction to both stack and reach before comparison against the engine's forward-model calculations. Stack reconciles within ±1mm engineering tolerance across all seven sizes. Reach shows 2.2–2.6mm data inaccuracies in the published values on sizes 47, 51, and 60, while sizes 49, 53, 55, and 57 reconcile within tolerance. Wheelbase shows systematic 2.1–2.5mm data inaccuracies across six sizes (47, 49, 51, 53, 55, 60), with only size 57 reconciling within tolerance. Trail reconciles within ±1mm engineering tolerance across all sizes.
