I have a Sugino crank (non-drive train side) that connects with a square tapered bracket, but is stuck. It's an older Bianchi frame. 1980's. The dude who I got it from forgot to tell me that the threads for the crank remover are COMPLETELY stripped. So, needless to say, a crank removal tool is null. I can get the bolt out, but the crank is pretty stuck. I don't really want to bash on it with a hammer. I think that may hurt the frame. Advice anyone?? Thanks!!
