• hello @mdcc_tester,
    I purchased a new 1" threaded fork recently and just noticed that the fork crown (headset is ck gripnut) is going down all the way without the need to be pressed. I don't think the gap is very big, I though I could try inserting a kind of shim made of aluminium can for example between fork crown inner diameter and fork steerer diameter just to get it to sit correctly ; I think once the headset will be properly set-up this could work. any thoughts on this? would you recommend another method? I have seen that Sheldon recommend making dents on the fork crown with a centerpunch but I do not have the proper tooling to do it. Thank you in advance!

    EDIT: I might as well try to do it more properly with this

  • I do not have the proper tooling

    The first tool you need is a measuring implement so that you know exactly what is wrong and by how much.

  • Yes considering I have found undersized crown races from ck available in -0.1 and -0.2mm I will try to measure as precisely as possible both the steerer and the crown race I have to pick the right item
