I was lucky enough to get hold of a set of chainstays/seatstays with I. S. Disc mounts. Purchased from Chuck at Rainbow. There's mention on here of him shutting shop! I also bought an NOS Screaming demon frame but this was, sold to a friend.That is a nice bike. I know I still ride one every once in a while (My two are still owned by friends). The bike still rides great. What did you do about the brakes? I see you have something other than the 22mm tab mount Hayes.
