would you say that a cat 2 rider is a professional? or are professionals always cat 1 riders....I was just wondering what categories you have to be in to be considered a "pro racer"...i know that obviously that riders in cat 1 and 2 are obviously not on par with pros such as discovery, CSC,... but still, what is the minimun cat that a rider must be in to be considered a "pro"....thanks
