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 RideDNA engine detected a geometric inconsistency between the manufacturer's published Effective Top Tube (ETT) values and the dimensional relationships implied by their published Reach, Wheelbase, and Front Center specifications across all five sizes. Because ETT is the sole dimension anchoring BB horizontal position in the forward model, an incorrect ETT produces simultaneous lockstep discrepancies in all three ETT-derived audit checks—Reach, Wheelbase, and Front Center—rather than three independent failures. Stack and Trail remained unaffected, consistent with the ETT-anchor hypothesis. Corrected ETT values were applied; the Published Geometry table retains the original published values and the Calculated Geometry table shows the corrected values in blue. The corrected ETT values range from 6.6mm to 9.6mm higher than the manufacturer's published specification, representing a significant data inaccuracy in the published ETT dimension.
