Fuji SST 2012 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.

Fuji SST 2012 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 Fuji SST geometry reconciles within ±1mm engineering tolerance across five of six sizes (50–58cm). Size 60cm shows a 5.2mm significant data inaccuracy in the published stack value and an 18.1mm significant data inaccuracy in the published reach value. The RideDNA Geometry Engine reconciliation checks confirm this pattern: size 60's published stack appears deflated by approximately 5.4mm relative to what the other published geometry parameters imply, and the published reach is inconsistent with the front center geometry at the manufacturer-specified fork offset. The seat tube angle progression shows two unusually large single-step changes (50→52: Δ−1.5°; 58→60: Δ−1.5°) that warrant verification, though the root cause cannot be determined from the published geometry data alone.
