• Hey,

    I just swapped my handlebars and stem on a bike and I'm failing to tighten the topcap into the expender plug. The top cap & expender are spinning around without getting tight :(

    Video to illustrate as I'm not very good with words: https://streamable.com/d52eab

    Any idea on what's going on and how to fix?

    Cheers

  • Looks like when you unscrewed it, the expander unscrewed rather than the cap. So half of your expander is probably somewhere at the bottom of your fork steerer.
