3T Ultra 700c 2026 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.

3T Ultra 700c 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 3T Ultra 700c geometry specification exhibits systematic discrepancies across all six sizes. Reach shows data inaccuracies ranging from 8.7mm to 12.9mm across all sizes. Front center shows significant data inaccuracies ranging from 8.9mm to 10.7mm on sizes 54–61, while sizes 48–51 reconcile within ±1mm engineering tolerance. Stack shows minor data inaccuracies of 2.3–3.0mm on sizes 48–51, while sizes 54–61 reconcile within ±1mm engineering tolerance.
