hi there, I have a problem, I have the back top right 4 bolt mount bolt is stuck in, i tryed it loosen the bolt and unfortunatly the bolt snapped and a bit is still stuck in the frame with about 5mm sticking out of it. This happened to me on my old czar frame and i would like to get it out due to i am wanting to build up a second bike with it. I already tryed to heat up the bolt and saw a line in the bolt and then tryed to turn the bolt using a screw driver but it would'nt budge. If anyone has any suggestions for how to get the bolt out all suggestions would be greatfully appresated. Many thanks Craig
