| reason | Cube publishes no defensible conventional equivalence for its letter sizes. CUBE prints a centimetre figure beside its Nuroad letters and it is a frame measurement, not a size name — and the Nuroad range proves it on its own: this crawl carries three different ladders under one range name. Nuroad C:62 is XS=43 S=46 M=49 L=51 XL=54, Nuroad EX / Pro is XS=44.7 S=47.7 M=50.7 L=52.7 XL=55.7, and Nuroad Race / SLX is XS=47 S=50 M=53 L=55 XL=57. One letter cannot be three sizes. Every one of those ladders also sits 2-6 cm below the conventional German scale, which is the signature of a seat tube on a compact frame, so mapping any of them would tell a 53 cm rider that a Nuroad M fits when CUBE's own dealers sell that bike as a 56. CUBE's numerically-sized ROAD bikes (47/50/53/56/58/60/62) are unaffected: they are numbers on the conventional scale and are used as they are. |
A shopper asking for: 54 → nothing compatible · 56 → nothing compatible · 58 → nothing compatible · 60 → nothing compatible
