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 Orbea Terra geometry specification exhibits systematic discrepancies across all six sizes. Reach shows 4.5–6.3mm data inaccuracies on sizes S through XXL, with size XS at 4.5mm falling just above the ±1mm engineering tolerance. Wheelbase discrepancies range from 4.0–6.3mm across all sizes, with the larger three sizes (L, XL, XXL) showing the most significant deviations. Trail shows 4.9–5.8mm data inaccuracies across all sizes. Stack reconciles within ±1mm engineering tolerance across the entire size run, confirming the manufacturer's published fork axle-to-crown length and head tube length values are accurate.
