Specialized Diverge 4 2026 complete geometry

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.

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: 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.

Geometry reconciliation applies a 48mm Future Shock steerer extension correction to both stack and reach before comparison against the engine's forward-model calculations. Stack reconciles within ±1mm engineering tolerance across all six sizes. Reach shows a 5.9mm data inaccuracy on size 52, with sizes 49, 54, 56, 58, and 61 showing 2.4–4.1mm data inaccuracies. Wheelbase and front center exhibit parallel discrepancies: size 52 shows 8.3mm and 5.8mm data inaccuracies respectively, while sizes 49, 54, 56, 58, and 61 show 2.1–4.5mm data inaccuracies. Trail reconciles within ±1mm engineering tolerance across all sizes.
