It's chromoly of some sort. I think the whole name for chromo is chromolybdenum so it's chromo. I've been told chromo "starts" at about 4130. That is, for something to be considered chromoly it's basically going to be 4130 chromo steel. I don't know if that's correct, but the frame is most likely a base chromo.
