| reason | Bulls publishes no defensible conventional equivalence for its letter sizes. BULLS publishes a rider-height chart only ('Körpergröße' -> 'empfohlene Rahmengröße', XS 135-160 … XL 185-200 cm) with no centimetre equivalence, and its own chart stops at XL. So no letter is mapped. One retailer dual label ('XXL = 60 cm' on an Alpine Hawk) is left standing as listing-specific evidence because it sits on the conventional scale and there is no manufacturer evidence that it is a measurement — but it is a single unverified claim and is recorded as a residual risk. |
A shopper asking for: 54 → nothing compatible · 56 → nothing compatible · 58 → nothing compatible · 60 → nothing compatible
Only listing of this configuration — nothing to merge.
