I have just order some new carbon fibre forks and simply just waiting for them to arrive, I have heard in order to use these forks I have to have a special carbon fibre star nut, I just wanted to know if this was true or not, just so if I need to buy the carbon star nut I can, or whether I can just use a normal star nut. :?

    The steerer tube is carbon?? If so then dont use a standard star nut - you will need an expander bung to spread the load without scratching the carbon. This sort of thing - loads around

    Carbon forks with an alloy steerer, normal star fangled nut.
    Carbon forks with carbon steerer, as WirralPaul says, use a bung. There's no shortcut, a fangled nut is not an option with carbon steerers.

    if the steerer is cf...

    as above, use a bung

    follow installation instructions carefully, depending on your stem and top cap you may need to use a short spacer, say 3mm, above the stem to get the correct clamping area on the steerer

    when cutting the steerer, use a blade designed for cf, and make sure you don't split away cf at the edges of the cut, if in doubt get the lbs to do it

    Indeed you can. It may not bother you but the bottom end of the fork is likely to be closed so once a star nut goes in, it may not ever come back out. Hopefully never a problem though.
