So. I was fettling with my bike tonight and decided to "sort" the slightly loose headset. No problems or so I thought but I get the feeling that when I installed it I over tightened it so when I unscrewed it today it took out most of the headset. Part of the expander is left wedged in the steerer, part dropped down and the rest came out.
If I could get the expander out I think I could fix it with some GT85 and some patience but not had any luck. Anyone else had this and if so, how do I fix?
