What do I put on the rear hub of a Cambio Corsa: A very good four speed block, or a mediocre three? Were there any four sp. C/Cs at all?
Another feather in the cap of the four is that it says "Firma Societa Italiana Catene Calibrate Regina", and "Marca Folgor Gran Sport" on it, whereas there is only an abbreviation of this on the three.
Thanks for your advice,
