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: red. 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 Van Rysel RCR Pro geometry specification shows systematic discrepancies across all five sizes. Stack reconciles within ±1mm engineering tolerance on all sizes. Reach shows a 6.6–6.7mm data inaccuracy in the published values across all sizes, and wheelbase shows a 6.4–6.7mm data inaccuracy across all sizes. Per the GEOMETRY INSIGHTS, the forward model used Effective Top Tube (ETT) as the geometry anchor to determine BB horizontal position — reach and wheelbase are both independently derived from this ETT-anchored BB position. The simultaneous and systematic discrepancies in both reach and wheelbase indicate the published reach and wheelbase values are not consistent with the published ETT specification.
