Specialized Tarmac SL9 2026 geometry chart

Source: Manufacturer geometry source

This profile is available for riders, but it is not currently indexed because its published geometry is not fully independently verified. Values marked derived are calculated by RideDNA; values marked published are transcribed from the manufacturer chart.

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.

The Specialized Tarmac SL9 geometry specification shows strong reconciliation for stack, reach, and wheelbase across all seven sizes (within ±1mm engineering tolerance). Front center exhibits systematic discrepancies ranging from 3.8mm to 5.4mm across all sizes, with the two smallest sizes (44, 49) exceeding the 5mm threshold. The RideDNA Geometry Engine reconciliation confirms this pattern: the published reach values are internally inconsistent with the published front center geometry at the manufacturer's stated fork offsets, and the published wheelbase and front center values imply chainstay lengths 3.7–5.4mm longer than the 410mm specification.
