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: 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 Cervelo Caledonia's published geometry reconciles within ±1mm engineering tolerance across all six sizes for stack, reach, wheelbase, and front center. Trail shows a consistent , within ±1mm engineering tolerance. The manufacturer's published specification demonstrates strong internal geometric consistency.
