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 Merida Mission gravel bike geometry specification reconciles within ±1mm engineering tolerance across all six sizes (XXS–XL) for stack, reach, and wheelbase. The forward-model calculations, anchored to the published effective top tube values, confirm internal consistency of the manufacturer's published specification. The fork axle-to-crown length is sourced directly from the manufacturer's published specification, enabling independent geometric verification of all primary dimensions.
