reason	Merida 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.
