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 Litespeed Arenberg / FI geometry specification demonstrates strong internal consistency across all six sizes. Stack, reach, wheelbase, front center, and trail all reconcile within ±1mm engineering tolerance. The manufacturer's published geometry forms a coherent and self-consistent specification.
