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 Giant Propel Advanced geometry reconciles within ±1mm engineering tolerance across all six sizes for stack, reach, and wheelbase. Trail shows systematic 1.2–1.5mm discrepancies across all sizes, within ±1mm engineering tolerance. The RideDNA Geometry Engine reconciliation checks reveal a Stack mispublishing pattern on size S, where published stack appears deflated by approximately 1.1mm relative to what the other published geometry parameters imply. One size (XS) shows an STA > HTA inversion opposite to the model-line dominant pattern — this minority inversion may indicate an HTA↔STA data entry swap and warrants vision re-audit of that size.
