    Help diagnosing BB creak noise

    I've got an 08 Mercier Kilo TT with stock cranks/BB and a powergrip pedal+strap setup

    Everything's been tightened down.

    With both sides, on the downstroke, I get a one or two short creaks.

    On the upstroke, I get no creaks. Backpedaling gets the same short creaks.

    I've checked my pedals and all the crank nuts. Is it just the crappy stock BB/cranks? They're truativ cranks btw. I've only had the bike for about two months.

    Stand up and pedal. Does it still happen? If so, chainring bolts. If that doesn't work, hammer to BB.

    If its a cartridge BB, did you grease the threads and the inside of the cup?

    Ok I used all my power and might to tighten the crank bolts, pedals, seatpost, even the stem setup and the creaking seems to have disappeared. Now I just gotta figure out why my handlebars creak when standing up to climb hills.

    Just so I don't have to start another thread, handlebars creak if they're not tempered right?

    Handlebars can creak for a number of reasons. If your stem has a removable face plate, loosen all of the bolts and retighten them equally, taking up the slack evenly across the faceplate as you tighten it, kinda like the lugnuts on a car. You want equal tension at the top and bottom. Also, if the bar is a different diameter than the stem (risers on a road stem with the wrong shims), it can creak.

    As for tempering, I have never heard of that.

    Oh that's probably it then, the top bolt is tightened more than the bottom. I'll fix it tomorrow. Thanks.

    Grease can't hurt. See what it does. I've found that a lot of cheap stems with 2-bolt faceplates creak when standing and putting a load on one side of the bars or the other.

    my friend has this same creaking and he complains about it all the time and he has a two-bolt faceplate.
    He figures once he upgrades to a thomson or a more secure 4-bolt faceplate in general, the creaking will stop.

    Well it turned out to be my quill stem adapter. I took it out today and regreased everything. I also took the time to dismantle everything else on my ride and regreased. No creaks whatsoever.

    grease the seat first, if that doesn't work, grease the pedals and the grips.
