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.

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.

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.
