My experience indicate resale value would probably be poor. Value in the bicycle market seems to be driven by drive by prestige, quality and rarity, in that order. Very few people have heard of Cambio Rino and consequently there is little prestige associated with them. This is compounded by the fact that they used their own components rather than Campagnolo. Generally, cyclists associate the quality of the frame with the tubing and/or level of components on it. Since the components have no readily associated reputation, they draw down the value. Now rarity is the one thing Cambio Rino does have, but it's not enough. It may interest a former owner of one or collector of oddballs, but most people will pass them over.
