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 Boone geometry specification reconciles well across stack, reach, and wheelbase — all sizes fall within ±1mm engineering tolerance for these checks. Trail shows systematic discrepancies ranging from 2.5mm to 3.5mm across all six sizes, indicating a data inaccuracy in the published trail values. The root cause cannot be determined from the published geometry data alone.
