    Thread tape on a BB?

    Has anyone ever installed a BB with thread tape or plumbers tape on the threads? I thought it would help seal it, and help against creaking and loosening. It's a new frame with nothing wrong with the BB, but I'm just thinking about preventative measures.

    A little bit probably would be ok. The tape is really intended to fill gaps in poorly constructed tap/fittings that come off large scale production lines and have very poor quality control compared with bike parts. The threads are also wider and deeper which help to 'disperse' excess tape where its not required.

    A good quality grease would do just as well

    If creaking and loosening is a problem threadlocker would be a better solution.

    Works very well against creaking.

    Always. I use teflon tape with copper antiseize on all my external BBs.

    I had a BB that always creaked whatever I tried and this was the only thing that fixed it. Since then I use this trick on all my BBs

    Loctite is probably not the best idea, a BB shouldn't loosen if it's well installed.

    I for sure use teflon on all my bottom brackets that give me problems in the creaking variety...

    Teflon tape plus grease here

    Like the title says. Even on my buddies Lynskey pro, which went together like butter.

    Should be using Ti-prep on a titanium bike.


    I've assembled many bikes since working at an LBS. Have only used grease on the BB threads, but made sure to use plenty. Never had a need to even try teflon tape.

    Loctite is actually recommended by Barnetts Bicycle Institute - but they recommend that along with installing at minimum required torque.

    I either grease or loctite.

    Good for them but I prefer not to. BB can be hard to remove, the last thing I'd want there is loctite. A BB will not loosen, drive-side is reverse threaded in most cases.

    I've spoken with a guy a few months back that has taken Barnetts class. I was told first hand that Barnett does some things are are not industry "norm" and when asked could not really give a definitive answer on why its done different.


    If you have to use Loc-tite to keep a BB from loosening, its either poor installation, or something is damaged.

    Most manufacturers only recommend the use of grease.

    they recommend loctite mostly for corrosion reasons. it works well for that, in reality loctite is expensive and not cost effective

    I'm surprised nobody has mentioned it.

    Get your BB Shell faced.

    Probably because it has nothing to do with the discussion at hand.

    Ya, it's a new frame, so I am thinking about preventative stuff.

    As has been said, as long as everything is in good condition and you use adequate installation torque all you will need is some lubrication on the threads.

    If for whatever reason you have problems with a BB loosening threadlock is probably the best solution.

    I use Loctite on just one side of one frame. The threads on that side of the BB shell got damaged so I install the bearing cup with less torque than you would normally use to avoid stripping the remaining threads. A dose of blue Loctite keeps it from backing out. Never had trouble removing it when I wanted to.

    It has a lot to do with it.

    If your BB shell isn't faced properly, it can lead to the cups coming loose, creaking, and bearings to wear out prematurely.

    Especially if it's a new frame.. make sure it's faced.

    Pretty much. If cups are creaking or coming loose, you should find the reasons why. Teflon tape is a bandaid type solution.

    You can extrapolate but the guy asked if people used teflon tape on threads. From there, nothing leads me to beleive he won't face his frame.

    Your correct. It's amazing how people can't comprehend what they read.

    I use Teflon tape & grease all the time on BB's. In my experience it does help with
    creaks if a bike is prone to do so at the BB.

    And I always make sure the BB Shell is properly faced.

    Just my 2 cents, I am sure others will disagree with me.
    Nobody cares...........

    Nothing led me to believe he was smart enough to face his BB shell if he's asking about Teflon tape fixing creaking and loosening.

    Sorry for trying to help by providing the correct solution to a problem.

    "Nothing wrong with the frame" doesn't really indicate that it has been faced, "Nothing wrong" is purely opinion, since some people... see big bike manufacturers, don't seem to think Facing and Chasing is important.
