I noticed yesterday that my bars are not right for me. They need to be angled more forward and a little higher wouldn't hurt either. I was just out looking at them and there is only one bolt holding them clamped on each end. There is also a small tit that locates them for the angle. Would I be making a mistake if I ground that tit off so I could change the angle on them? I wouldn't ask but, these have only one clamp bolt per side whereas my old bikes have had two. The tit is so little that I hoestly can't see it doing much. ??? HELP!
