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.

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.

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