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 5 geometry specification reconciles within ±1mm engineering tolerance across all six sizes for stack, reach, wheelbase, front center, and trail. The engine's forward-model calculations, anchored to the published Effective Top Tube length, show maximum discrepancies of 2mm (reach, size 48) and 1.9mm (wheelbase and front center, size 48), with all other sizes reconciling within 1mm. This level of agreement confirms the internal geometric consistency of the published specification.
