[1] Different tire and rim combinations will result in different clearances.
[2] Depending on drivetrain configuration, tire clearance may be limited by the chain and not the frame.
[3] Listed chainring clearance is worst-case scenario. Clearances vary widely depending on components and configurations.
[4] Suspension fork length listed at full extension (not at sag)
