Trying to remove the headset to replace the bearings. For some reason I can't get the top cap off. I have loosened the stem bolts and then loosened the top cap bolt, but not the top cap bolt is turning but not threading itself out.

Hope that has explained it (little confusing maybe!).

most likely explanation is that you have a wedge expander in your steerer and it's worked loose, so the top cap bolt is turning the expander too.

if it is loose, you should be able to drift it out from below if your fork has a hole at the crown

Thanks Dave.

All sorted, you were right, the whole expander was turning!
