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 Salsa Cutthroat C geometry specification reconciles within ±1mm engineering tolerance across all five sizes for stack, reach, and wheelbase. The published geometry demonstrates internal consistency with the manufacturer's stated fork specification and reference tire. The RideDNA Geometry Engine reconciliation checks reveal a systematic 1.8mm stack deflation pattern across all sizes — the published stack values are approximately 1.8mm lower than what the other published geometry parameters imply — but this residual falls within the ±1mm engineering tolerance of the forward-model consistency audit.
