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.

The Giant TCX Advanced geometry specification reconciles well with the RideDNA engine's forward-model calculations across all five sizes. Stack, reach, and wheelbase all reconcile within ±1mm engineering tolerance across the entire size run. Trail shows a systematic 2.6–2.7mm data inaccuracy in the published values across all sizes. The RideDNA Geometry Engine reconciliation checks confirm strong internal consistency among the published dimensions, with all back-calculated values falling within ±1mm of their published counterparts.
