Source: Manufacturer geometry source

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: yellow. 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 Ridley Noah Fast geometry specification shows strong internal consistency across the size run, with stack and reach reconciling within ±1mm engineering tolerance on all five sizes. Wheelbase shows 4.4–4.8mm data inaccuracies on sizes XXS and XS, while sizes S–L reconcile within tolerance. The manufacturer has not published trail values; the engine forward-computes trail using the manufacturer's stated 700 x 30c reference tire.
