Ummmm, not really. You can still give a 'general' idea for how a bike handles based on the design of the fork and frame itself. One of the best descending bikes I've ever ridden was a Pinarello Prince; that was due mostly to the Onda fork design, awesome fork and coupled with a fat ass front end and rear end designed like the fork, man that bike was fast. By the way, its not mine.
