    Converting 1 1/4 threaded to threadless-anyone make a converter?

    Howdy,
    I have a Manitou FS that has a threaded fork with a long ATAC quill stem.
    I have a Manitou threadless stem that I would like to use.
    I know Profile makes a 1 1/8th and 1" converter but no 1 1/4.
    Does anyone know if there is another mfg that makes something similar?
    Thanks

    That would work, but if the threadless stem is also 1-1/4" you'll need a shim between the adapter and the stem.

    Thanks, but the Threadless Stem is 1 1/4 as well so......I would have to shim the stem.

    Thought about replacing the crown and steerer but a am afraid to remove the headset and replace it. I can hear the "crack" in my nightmares.

    Steve, if I figure it out I will PM you.

    Know any machinists? Making a shim for the Nitto mentioned above would not be too hard. I have made several for handlebars and stems.

    What kind of headset are you running? I assume not a King since it would be easy enough to leave the cups in the frame and just convert it to a threadless setup.

    Unless he wants to keep the fork with the threaded steerer, then the headset doesn't matter.

    He could swap the crown/steerer to a threadless one, and keep the fork.

    So, as luck would have it, the Manitou stem that I picked up is 1 1/8th, not 1 1/4th like I was told. What that means is, I ordered the Nitto column, installed it today and with the stem and it works perfect. It has a XT headset and would love to swap it but it scares me to think about taking it out and replacing it. I can just hear the cracking sound.
    Thanks for all the replies.
    I will post photos once it is done.
