I have a deda expander plug (like this) I’ve just fitted on a carbon steerer. Having tightened the plug first, set the preload, tightened stem, and then tightened top cap again (as I would for star nut). So now when I take top cap off, rather than just unscrewing itself, it also unscrews the expander bolt which it is screwed into, separating the expander bung, and so also when I screw the top cap back in, it is inside the expander plug bolt and expands the plug, rather than just setting the preload alone, if that makes sense.
Is this just how it goes with expander plugs or am I missing something? Did I set the top cap bolt too tight after tightening stem? Do I just need to separate the top cap and expander bolts each time I remove fork?
Stems can creep up the steerer. Tightening the top cap after the stem can possibly help holding the stem down while not putting more preload in the bearings.
