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: yellow. 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 Trek Checkpoint geometry reconciles well across the size run, with only size XS showing minor discrepancies in reach (2.6mm), wheelbase (2.7mm), and front center (2.3mm). Sizes S through XL reconcile within ±1mm engineering tolerance across all checks. Stack reconciles within tolerance across all six sizes. The manufacturer publishes all standard geometry dimensions, enabling full independent verification of the published specification.
