can you fill me in here? what are key differences, what are the dates.......what is the relative value, how long to they last? I'm specifically referring to cranks. I have an opportunity to buy a superbe or a superbe pro crankset, without knowing the pricing yet, which do you think it better bang for buck?
thanks. It's to go on a specialissima, originally a triple, but I can't hang with triple, too much Q
