reason	ROSE publishes no defensible conventional equivalence for its letter sizes. ROSE publishes a rider-height range per letter size and nothing else — no geometry table at all on its product pages, and its own Größenberatung covers clothing only, not frames. A height range alone does not establish which conventional centimetre size a letter corresponds to, so ROSE bikes appear when a shopper picks a letter, not a centimetre.
