"... but whudooino?" Probably as much or more than I do. I just find it curious that chainrings are almost always al, even when they are as small as 24t, but cogs are virtually always steel, even when they are bigger than that. Even when those cogs are on separate al spyder to "save weight". I mean I don't really care, but it seems a bit odd.
