• Taken the fork off and inspected all the threads on both the headset and the fork. Everything seems fine to be honest? Maybe a little dirty I suppose but it all looks in good condition.
    Only thing is noticed is the top nut (not sure the actual name for it - the upper most nut where the branding usual is, in the case 'Record Campagnolo') is not completely threaded on the steerer as I have a single spacer underneath. This is like 2 threads at most so I can't imagine its causing any issue but it is something I noticed.
    I might swap out the headset for something else just to try something, as I have no other ideas really.

  • How have you inspected it? You won’t really know unless you try and thread another headset down the fork threads and compare them. If it threads in tighter than the one that keeps on coming undone then you know the threads are prob worn.

    I would use a thinner spacer on the fork and see if that helps at all

  • Or no spacer at all? I’ve run them like that fine in the past but happy to be told that’s a no no. Just make sure the top nut isn’t bottoming out onto the top of the steerer and is tightening against the spacer/nut below it.
