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 Lauf Uthald geometry specification shows 0.0mm deltas across all checks and all sizes. This result reflects the RideDNA engine carrying through the manufacturer's published values directly, not independent geometric verification. The manufacturer has not published effective top tube (ETT) length, which prevents the engine from computing full forward-model geometry. An accurate and complete geometry specification from the manufacturer — including ETT — would enable full independent geometric verification of stack, reach, wheelbase, and front center.
