Fair enough, but cycling with 10% body fat would have you laughed out of the Peleton....  There is a well known story of Tyler Hamilton back in his drug days being told by Michelle Ferrari (notorious drug doc and shitlord extraordinaire) that he was too fat (he was already a pro rider at world class level)...when asked what would determine him being low fat he was told when the sleeves of your cycling top flap in the wind....that's a brutal assessment....some of these guys hover around 6-8% during the season.
