Just the other day I went to buy a 20 dollar tange champion Japanese schwinn super sport for the suntour barcons.. going to use most of the components for a touring bike I'm building for my girlfriend. The guy was so happy I knew a few things about his old bike that he ended up giving me a trek (my gfs size!) 520 frame and a NOS suntour cyclone derailer. Great day. So yes barcons for the win.
