A size-by-size geometry profile with manufacturer provenance and RideDNA consistency-audit context. Use the complete table to compare fit and handling before opening the interactive tools.
Source: Manufacturer geometry source
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.

Overall consistency: red. 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 3T Racemax 2 Italia geometry exhibits isolated discrepancies on size S, where stack shows a 4.9mm data inaccuracy, reach shows a 3.3mm data inaccuracy, wheelbase shows a 15.4mm significant data inaccuracy, and front center shows a 14.6mm significant data inaccuracy in the published values. Size XL shows minor discrepancies in wheelbase (4.7mm) and front center (4.1mm). Sizes M and L reconcile within ±1mm engineering tolerance across all checks. The anomalous front center non-progression between sizes S (609mm) and M (607mm) — where the engine's calculated front center does not show the same decrease — provides independent evidence of a data integrity issue in the published front center values for size S.
