Yeah, so you get some of what you need from your diet, but maybe not enough, and hence the BCAA supplementation.
This raises a related question about how much protein (and the sources of protein) endurance cyclists need. The general population supposedly needs on the order of 50 grams/day and many consume more protein than they need, but endurance athlete need more, and the additional amount needed is, to my knowledge, poorly quantified. Well, of course it depends on how hard you exercise, among other things.
