Published geometry by size

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.

Audit context

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 Cannondale Synapse Carbon published geometry reconciles within ±1mm engineering tolerance across all seven sizes for stack, reach, wheelbase, and front center. The manufacturer publishes trail values, which the engine accepts as authoritative — the implied tire derived from those values is 700 x 41c (41mm), closely matching the bike's gravel/endurance road category. The RideDNA Geometry Engine reconciliation checks confirm internal geometric consistency across all sizes, with all five checks passing green.
