Hi all

Just a quick question.....do you usually get a star nut with brand new forks or is it a separate buy needed?

Cheers

    depends on the forks.

    normally with the headset.

    i guess you will need to get one.

    I'll get one to be safe, only a couple of quid.

    always seem to come with Rockshox,

    My revs from merlin didn't, then again they were in a plain box, no shock pump too (which I think some come with?).

    Quick piece of advice if I can - I've had a read of Park Tools.

    I haven't got a specific nut install tool so am probably going to have to improvise - has anyone got any tips as I don't want to balls it up?

    Should I forget the star nut and go for one of the expansion bolt and sleeve jobbies?

    Thanks in advance

    bolt, thread two nuts on. lock them together screw on star nut. fit good leather glove to left hand. if left handed fit it to your other hand). Offer the starnut bolt to the fork and hit it with hammer.

    see the glove was useful as that would have hurt.

    unscrew bolt. fit fork fit reast of headset and then the steerer and any washers and finally the top cap.

    now go find that glove.

    the bolt and nut are a makeshift insertion tool.
    and the correct way

    do not try to bodge a star nut in, if it doesn't go in straight you are in a mess

    get a hope expanding bung

    worse than an off center star nut.

    and if it is at an angle it is easy to straighten.

    Agreed + potato

    Thats how I did mine, no bother and just give the bolt a wiggle to line it up square! PFFT these none mechanically minded types eh??

    I use an old V brake block, screw it into the starnut and tap it in. You can hold the tip of the block, so you don't need a massive glove (providing you have a bit of co-ordination), and if it starts going skew you can spin it and tap from the opposite side.

    Brilliant thanks!

    Last question I promise ;-)

    I thought by undoing the top cap and removing the stem the forks would jet drop out but they don't?

    They are rockshox pike 409's on a 2010 Marin wolf ridge with the standard FDA headset that it came with.

    Cheers for the help!

    There is a compression ring. Push the front end down sharply and it may pop up enough to make it easier. Or just give the top of the steerer tube a gentle whack with a mallet.

    There is a wedge in the top portion of the headset which helps to sit everything square when compression is added and take up any room left over from dodgy manufacturing processes.

    This thing sticks, but doesn't require much of a sharp tap of the hammer on the fork steerer (whilst holding the frame) for it to budge.

    Just be careful bits of headset don't go flying onto a dusty/gritty floor. :lol:
