reasonMerida publishes no defensible conventional equivalence for its letter sizes. Merida publishes geometry measurements plus a body-measurement calculator (SmartFit) and no centimetre size name. Its letter scale does not line up with the market's either — the Scultura runs 3XS, XXS, XS, S, M, L, XL with no M/L and seat tubes of 400, 435, 458, 481, 501, 521, 550 mm — so neither the letters nor the measurements can be mapped.

A shopper asking for: 54 → nothing compatible · 56 → nothing compatible · 58 → nothing compatible · 60 → nothing compatible

Identity

Only listing of this configuration — nothing to merge.

Provenance — why we believe each fact
