    Mysterious squeak

    Need help killing an annoying squeak (not creak!)...

    Setup:
    Ti hardtail
    Singlespeed
    XT crankset
    KMC X9 chain
    No-name tensioner
    Chris King hub
    32 t Race Face chainring
    16 t cog with a conversion kit
    Xpedo pedals - platforms

    When it happens:
    It happens in synch with the revolutions of my pedals - not when coasting
    Not every revolution - only once every 3-4

    What I have done so far:
    Injected some Park Tools grease into my pedal axes
    Greased the pedal threads where they meet the cranks
    Removed the crankset and cleaned it, put some grease on it
    Cleaned and oiled my chain

    There are no other drivetrain parts that it could be besides my BB...

    Any advice, ideas?

    Thanks.

    Are you wearing a hydration pack by any chance? I chased a squeak for months only to find it was the chest strap buckle on my hydration pack.

    Thanks both for your answers, will check all those.

    Nope not related to hydration pack but I will keep that in mind. Once I had a squeak that ended up being my shoe. ha

    My vote is for stiff link in the chain. The symptoms fit - only when pedalling, every few revolutions. I get the dreaded squeaky link regularly, and take it as a sign my chain needs a good clean and re-lube. A superficial clean doesn't always do it, need to work the lube deep into the offending link. Sometimes its a flake of metal jammed between the plates, or a tight rivet - which can be loosened with a chain tool.

    OK I took it to a shop, one I had never used before, and explained the situation.

    They checked my chain, tensioner, cranks, and opened my bb and cleaned it all up.

    I came back and tested it, sure enough, the squeak was right there, loud as ever.

    Then they had the bright idea of changing the pedals (wouldn't you do that first?) which of course solved it. It was my left pedal.

    But I needed to have my bb cleaned anyway!
