    Expander bolt - overtightening

    I was tightening the expander bolt on the stem for a mountain bike with a Judy DH fork. I guess I overtightened it, because I heard a crack sound. Anyway, I took the expander bolt off as well as the fork and examined for cracks. Nothing visible. I reassembled, being careful to only tighten the expander bolt until it was snug. So, is everything a-okay, or did I miss something?

    Expander bolt implies threaded HS and quill stem which ought to be a bit more than snug. If it is a threadless setup,with a plastic top cap that could have cracked, if cranked on too hard. Since sydney can't see it, he ain't gonna tell ya everything is hunkey dory.

    Yes it has a plastic top cap, but I can't see a crack anywhere. Not on the top cap, not on the fork, and not on the visible portion of the expander nut inside the fork.
