So I recently had to turn the handle bars on my bike sideways to fit it into a bike box for a train. When I was rotating them (even after loosening the stem bolt quite a bit) I heard kindof a crack. They turned fine and I tightened them back up, but when I was trying to get it back to normal, I realized that no matter how much I tightened the bolt, the stem and bars still come out of alignment with little force. I think it has something to do with that little angled nut thinger down in the stem, but I don't know what to do about it (besides taking it to the shop)
I had this happen to me a few weeks ago, I kept tightening and eventually the stem bolt broke. Little bugger of a nut would NOT tighten. Got a bolt/nut from the parts bin, installed, and tightened up and worked like normal.
If there is no tightening, the nut has dropped, if it is tight but just not tight enough, remove it and replace.
Cool mans. Yeah, I did the flip the frame thing and it caught the wedge (i found out what the thinger was called), but the stem has still been loose. I'll just dig through my old parts and find a new one and see what happens. Thanks!!!
