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: 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 Specialized Crux 5 geometry specification demonstrates strong internal consistency across all six sizes. Stack, reach, front center, and trail reconcile within ±1mm engineering tolerance across the entire size run. Size 49 shows a 2.2mm wheelbase data inaccuracy; all other sizes reconcile within tolerance. The RideDNA Geometry Engine reconciliation checks reveal a systematic stack inflation pattern across sizes 52–58, where the published stack values are approximately 1.3–1.5mm higher than what the other published geometry parameters imply.
