"New" does not mean "optimal." 47 units prove it with numbers.
A bicycle fresh out of the box arrives with a factory mechanical state that is almost never the optimal one. This dataset diagnoses 47 new bicycles (pre-use) across five failure vectors, each with its quantified impact in watts, braking distance or tolerance deviation. It is the basis of the pre-use diagnostic framework (PDI).
| Vector | Parameter | Factory | Optimal | Impact |
|---|---|---|---|---|
| V₁ Chain lubrication | Power loss at 250 W | 6–10 W | 3.4–4.0 W | −2.6 to −6.6 W recoverable |
| V₁ Bearing lubrication | Kinetic μ | 0.05–0.10 | 0.01–0.03 | friction 3–5× lower |
| V₂ Spoke tension | Variation between adjacent | ±20–30% | < ±10% | asymmetric wear, fatigue |
| V₃ Hydraulic compliance | Stopping distance | +25% vs optimal | reference | +1.75 m at 30 km/h |
| V₄ Assembly torque | % out of range | ~40% | 0% | micro-crack risk in carbon |
| V₅ Total drivetrain loss | Cumulative power loss | 7.5–13.5 W | 3.9–5.5 W | Δ = 3.6–8.0 W recoverable |
// Aggregated consolidation. Reference values come from published Park Tool criteria and from the PBMA Pre-Delivery Inspection Standards; factory conditions, from consolidated specialist-workshop reports, as declared in the supporting white paper. What BikeLab contributes is the five-vector framework and the quantification of its impact.
Module_02 // ReadingThis is a documentary consolidation, not an in-house measurement campaign, and that is worth stating up front. The reference criteria are public: Park Tool for truing and tension tolerances, the PBMA Pre-Delivery Inspection Standards for the delivery protocol, and consolidated specialist-workshop reports for factory conditions; all three are declared in the white paper, which is the DOI-bearing document of record. What BikeLab contributes, and what was not in any of those sources on its own, is the five independent vector framework and the quantification of its aggregated impact in watts and in braking distance. There is no per-unit raw set, and that is why none is offered.
Module_04 // Record (cite this)The set is illustrative of new mid/high-range bicycles and does not claim population-level statistical validity: it quantifies real vectors from published criteria and from factory condition documented by third parties. It does not replace an instrumented test under an in-house protocol, and is not presented as one. Provisional by design.
