My simple Front Sprocket Fix

[pointer2null]

I understand what you're saying. One of the reasons I'm not too owrried is on both the sprocket nuts I've had they both seem to undo one/two threads worth but then never seem to get any worse. It seem like when the pressure is reduced there isn't enough deformation in the thread to allow it to jump again.
In order not to tempt fate though, I will check it this Saturday.
