A quick question on form: Does having longer or shorter legs give a cyclist an advantage over someone with "average" length legs? For example, with running, supposively one with long legs can outstride others (especially on down hill). Also, having smaller feet makes for quicker turnover when stepping. (I'm sure none of this makes any substantial difference over say, being fit, but I was just curious.) This is of course assuming the bike is "perfectly" fit for the individual. Thanks!
