A serious question for a change!

Can I convert a 1" threded steel fork / steel frame to 1" threadless aheadset?

i.e. remove steel fork and threaded headset.

Buy 1" carbon fork + 1 " aheadset and fit.....?

Anyone got any ideas/experience?

Cheers

    I know you can get adaptor stems, with an expander bolt to fit into a threaded fork steerer, but allow an Aheadset stem to be fitted.

    As for actually swapping a fork with a threaded steerer for one designed for an Aheadset, to start with, you would need to find a headset bearing that would fit into your head tube - I don't know whether the two systems use the same diameter, though. Assuming you can find a suitable bearing, then I can't see why it wouldn't work, but I'm guessing they are pretty rare.

    EDIT: This one needs a Ø30.2mm cup in the head tube, so if you can measure your head tube accurately, you'll have an answer.

    Yep.

    To convert from threaded to A/Head you'll need...

    A head stem
    A head forks
    A head err headset

    That's pretty much it.

    @Mark,

    Thanks for confirm - figured as much.

    My only concern is frame steerer tube thickness and getting the 1" aheadset to fit.....

    It may be a guestimation!

    1" threaded should be staright swap for 1" ahead.

    I'm looking for a nice set of 1" carbon aero forks at the mo.

    Surely threaded stems are prettier though.

    :lol: Having seen the pics of your new steed, I'll concede that an alloy quill stem would look a bit out of place.
