  • Headset expander for carbon. Same as aluminium ?
  • I don't like star nuts, I prefer the Hed Doctor.
    This FSA one looks the same as Hope, but cheaper.

    It says it's for carbon forks though.
    Are carbon steerer tubes a different inside diameter to aluminium, or will it fit the same ?

    Someone must know. 😕

    Yeh it'll work. I've used a similar one on an ali steerer.

    The one I fished out of my carbon road steerer was a metal wegde assembly like above – just dont over tighten it!

    Thanks Gary.
    Foxy, did it then fit in an ali steerer ? Not that I don't beleive Gary, it's just that it's nice to have a second opinion. 🙂

    TBH I am not sure – I took it out but have not tried in my alu steerer as already had a hope head doctor and my new carbon road frame came with a "bung" it certainly wont a be bigger diameter than a std head doctor so you may have to crank it tighter?

    What about this:

    Carbon steerers tend to be a lot thicker than alloy ones, so it may not tighten sufficiently.

    Why would the one in that link be any different?

    It might be a smaller diameter to better fit thicker steerer tubes.

    Not certain, just a possibility.

    For internal diameters from 23.5 to 25.4 mm

    Gary I was comparing them as one in the list said fits both alloy and carbon steerers!

    Scroll down the list 🙂

    Why do you keep adding links to headset bungs for carbon steerers, the op is using an aluminium steerer.

    Just trying to find a cheep bung and to answer his question Gary?

    i.e. one says : For internal diameters from 23.5 to 25.4 mm

    so maybe he can go measure it?

    Fair enough, but the 2 I've used fit ali steeres

    OK Gary – he just wanted another person to say yes before he went for it – I was just trying also to say it should be OK 🙂

    Suppose he could always send it back. Think I used the one inch M:part one from wiggle.

    Thanks for the replies, looks like it's worth a try then as some expanders fit both carbon and ali, they must all be near enough the same size.
