I've got a persistently loose headset, and when I went to look into it, I find the star fangled nut flush to the top cap. It seems that all of the roadside adjustments that I've made have merely pulled up the star nut.
Why did this happen, and what can I do to fix it? I'd rather keep the same star nut if possible, as I want to get this bike ridable tonight.
It's an Aheadset with a Salsa topcap.
