    The last Loctite I bought (641) I got on e-bay for £3.50.

    Emmm i sorta need it today.

    rebuilding my FSA ceramic mega-exo BB and it says:

    "Tip: Use a small amount of green loctite 609 or 620 between bearing and cup. Doing so is better than grease at reducing possibility of dirt contamination and creaking between bearing and cup."

    Any local stockists or?
    Impact of racing on one without green loctite?

    Not done much with FSA. It is threaded or press-fit?

    If threaded, just use anti-seize, grease or whatever until you can get the proper stuff.

    I know with press-fit BB-86 (SRAM/Truvativ) the plastic cups are deformable which means re-doing it later isn't a good idea.

    Press fit.

    Not sure what you mean about plastic cups being deformable?

    I don't really want to risk a mechnical at the weekend so if I don't get it I'm thinking a DA BB instead (already on bike) but I prefer the way my Ceramic spins. Whether that translates to free speed or not I do not know.

    EDIT: This is what I need.

    With press-fit SRAM/Truvativ, the BB cups are made of deformable plastic. So you fit them and leave them until the BB needs to be replaced. If you pull and re-fit the BB, the cups are not as tight and they can creak (even more).

    I vaguely recall the internet telling me that the worst creaking is from metal press-fit cups on a carbon BB shell, and that's the application where Loctite 641 is recommended (it isn't recommended for plastic cups). I bought it anyway, but didn't use it as I discovered the creaking was from my freehub. :rolleyes:

    What are the FSA cups made of?

    Metal :)

    Fairly snug fit but I can't affort a failure.
