    Carbon steerer compression plug slipping

    Hi,
    My compression plug lifts out a little when I try to preload my headset. I have a carbon steerer and don't want to expand the plug any more than necessary. I also have the Tacx Carbon Assembly Paste (gritty grease) which I use for my carbon seatpost/alum seat tube. Should I use this paste on my compression plug and inside of the steerer? Will it help or should I keep it dry and just tighten up the plug?

    Thanks,
    Scott

    Yes, you can apply the taxx compound inside the steerer of the fork. I did it on both my bikes, works great!
    Good luck!
    Play & ride!

    won't hurt..

    The paste won't hurt, but obviously you haven't tightened the plug enough. I've never used assembly paste on anything and never had slippage.

    Clean everything with rubbing alcohol. No grease, no problem.

    how tight's tight enough

    Is it likely that an expansion plug can blow out the top of a steerer? Has anyone seen this happen? I mean I know it's possible, but it seems like you'd really have to crank it to burst the steerer.

    How tight is tight enough for a carbon steerer? I just installed one. I snugged it up to what 'felt' right. I didn't crank it, but it's tight.

    Cannondale which uses an FSA expander recommends 6.8nm = 5 foot pounds for the expander inside the carbon steerer of the Systemsix.
    Get a torque wrench, and 6.5nm should suffice.

    Profile Design expansion plug

    I just bought this plug to replace my old one.

    I'm hoping that it'll require less torque to hold in place. Plus, it's taller so it'll provide more support for the bottom bolt of my stem.
