    Changing from a 1 1/8th fork to a 1.5

    I bought a fork with a 1.5" steerer for my bike which has a 1.5" headtube and is currently running a reducer headset. In order to make the new fork work, I have already bought a 1.5" stem and a 1.5" headset. Is there anything else I will need to make the conversion work or am I all set?

    Do you have 1.5 spacers and a 1.5 star nut (probably came with the headset but maybe not)? You should be all set.

    The star nut comes with the headset and I think I should be able to get some spacers. What about the crown race? will that still work?

    Did you not get a crown race with your headset?
    Was your old fork tapered or straight up 1-1/8?

    Yes, the headset should come with a crown race as it has to match the bearings in the headset. You should be good for the conversion.

    Didn't see you mention the stem. You'll need one in 1.5 as well
