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 TCR Advanced published geometry reconciles within ±1mm engineering tolerance across all six sizes for stack, reach, and wheelbase. Trail shows discrepancies ranging from 1.2mm to 2.0mm, all within ±1mm engineering tolerance. The RideDNA Geometry Engine reconciliation checks reveal a systematic stack mispublishing pattern across four sizes (XS, S, M, ML), where published stack values appear inflated by approximately 1.5mm relative to what the other published geometry parameters imply. One data quality flag warrants attention: size XS shows STA > HTA (74.5° vs 71°), opposite to the dominant pattern across the other five sizes — this minority inversion may indicate an HTA↔STA data entry swap and a vision re-audit of that size is strongly recommended.
