    Either. Most headset come with something or most bikes already have something fitted so use them.

    starnut nice and simple and does the job..

    those expanders like those stupid head doctors are a waste of time.. starnut fit and forget.

    Yeah the star nut is in my old fork, my new fork didn’t come with a star nut; is that right?

    Plus I don’t think it will be a good idea to hammer out the star nut in my old fork, as it will surely ruin its integrity, and for 99p for a star nut, surely I will be better off buying a new one?

    P.S. the old fork is brand new, but not as could as my new one.

    Ahhh so it is a new fork. Why did you not say so? It could have been for a new build or.....

    New Star nut.

    I'm also thinking about getting a new stem and handlebars, so I might be better of getting an ‘expander’ as I don’t fancy purchasing a stem and handlebars at the moment, rather wait until I have extra money in a few weeks.

    Just wondering how the ‘expander’ holds up? Do they hold as good or better? Do they brake easy?

    A new stem etc makes no difference. Once the starnut is in, it's in. You don't need to take it out to change things unless you cut the steerer down, in which case you can just knock it in a bit further.
    Starnuts work perfectly and are really cheap. Expanders are a pain in the ar5e. Only used one in a carbon steerer, but it was annoying. They don't work any better. Just more faff.

    thats what i was thinking...

    in my experience the head doc was total censored . (the iedea is clever) but in reality they just not as good as a star nut.
    mine kept coming loose constant play in the headset. remove topcap and retighten the bolt inside then put the topcap on and nip up, was a pain sometime everyride or everyother ride..

    i never had to do that on a star nut..

    like mentioned above starnuts are cheaper and less hassle..

    i'm sure someone will ealong to sing expanders praises ect.. but in my eyes why spend more than you have to on an inferior product.

    Expander= cost more, weigh more, do same job

    Just suppose an expander worked loose, as the bearing compression is maintained by the stem bolts that would have no effect, in fact once the stem bolts are done up, you can take the top cap off and throw it away if you feel like it - so that bit is bunkum.

    After Sunday I have replaced my Hope expander with the simple starnut, make sure you get the starnut seated correctly i.e straight.

    Expanders are used for carbon steerers these days anyway, so they have their uses.

    Sorry, didn't mean to imply they had no use, just only a relevant use!

    My Onza forks use neither but come with a neat cap that screws into the top of the internally threaded steerer...now that IS a good idea!

    when i had the head doc on my pace frame, i could feel when it came loose, could feel it.. (like a knocking) it always turned out to be the head doc in the sterrer tube.. i would tighten it back up refit and tighten the topcap redo the stem bolts and it would be fine again.. untill the next time.

    I've been running head doctors for 5 years, they came with hope headsets. I've not had a single problem with them, when using them for XC use.

    I always throught that the top bolt was only used to put your forks, headset, stem under compression before you tighten the stem bolts. Then in theory you could take your top cap off (you wouldn't as it would make a nice hole if you fell off).

    why dont you try this then on your next ride to see if it's true... :P :mrgreen:

    as i said with the head doc i could always feel when it came loose even with the stem bolts still being tight.

    Why not use an external expander instead? Like the ones made by Exotic (CarbonCycles).

    No need to loosen the stem at all with these and can be adjusted in just a few seconds by your hands (not tools required).
