My theory is that that's what causes baggy short wearers to cross over into the Dark Land of Lycra--certainly did it for me. When I noticed that the parts of my legs that used to be, um, jiggly were now muscle, suddenly Lycra seemed like a really good idea. The old "if you've got it, flaunt it" principle in action, I guess.(Please note this only applies during saddle time!) Of course, the fact that Lycra is very comfortable on the bike doesn't hurt either. Similarly, when I noticed that my stomach was going in rather than out when I bent over I developed a sudden need to replace my baggy T shirts with Euro cut jerseys. When your physique starts looking better than it has in a decade or four, you get these strange urges.
