    when headsets strip

    It appears that the threading on the topmost portion of my FSA headset is stripped, or something.

    When attempting to tighten the locknut, it slips. It doesn't spin around freely, but it's definitely loose and after riding a few miles must be tightened up again (as far as it will go before it slips - it never gets too tight).

    Can I just replace the top sections of this headset with another? are these things universal or what?
    Anyone had to deal with this sorta thing before?

    I'm assuming that this is on the pursuit with a 1" threaded headset?

    did you check to see if it's the threads on the headset or on the fork?

    Do you have enuf thread on the fork? You can use any threaded locknut with it. If you have stripped it out I would recommend a steel one.

    i had that same problem (or at least it sounds very similar) with an old headset once. i dunno how but the LBS fixed it with no new parts. i think it involved locktite...

    naw, this is the GT. upon clozer inzpection I found the telltale hair-thin strands of metal inside the locknut. didn't see that before - maybe the LBS could hook me up with one and I be good to go.

    (I hope it's that easy - but it's been a rough week on yours truly o my brothers)

    Ok I should learn to read. If it never gets too tight but slips constantly then there is something wrong with the threads somewhere.

    One thought would be that you don't have enough threads on your fork and all the stress is taken by a few threads on the locknut, which may have failed. Pull the locknut off and look at the the fork threads and the locknut threads. Striped threads should be obvious.

    Also check you have a situation like in the diagram below. You want as much of the locknut to thread on to the fork column as possible while still leaving a gap.

    I'll leave my original post in just case and so I can be mocked.

    Orig bit
    ---------
    I bet you need a spacer under the locknut.

    The top locknut is probably bottoming out on the top of the fork so while it gets tight, its not not actually contacting the cup/cone together and so everything is still loose.

    Pull your stem out. There should be a small gap between the top of the fork and the locknut.

    See attached picture for what it should look like. Read the text at:

    Unmatched threading? English thread VS Italian thread VS French thread

    It was the locknut. Threading was screwed up. Things are good for the moment.

    Backstory on this: bought the frame with headset, checked it over and it seemed okay at the time. May not have been the case. Replacement works out.

    Thanks for your help & advice!
