T 2000 Squeak

I've got a 2001 Cannondale T2000 that I bought new. It has an annoying squeak when I'm applying a fair amount of torque to the pedals, especially noticeable when climbing a hill. A shop took out the bottom bracket and regreased everything. The shop guy thought it was likely a minor squeak magnified by the frame. It seemed to disappear after he was done... for about 40-50 miles, and I've not really addressed it since then. So what's the weak link to investigate here? The cranks? The bottom bracket?

Should I put this in another forum? I thought I'd start off here, where people were more apt to be familiar with the T2000.

Did you check the crank bolts?

I have an older C'Dale mtn frame that used to squeak as you say. I have been told, and I think I agree, that the aluminum frame helps to amplify the squeaks. I dismantled the bb, cleaned all the grease off all the threads: pedals, crank bolts and bb shell; and re-assembled with an anti-sieze compound. Everything was quiet after that.

My bike (not a Cannondale) developed a squeak similar to yours. I took it to a bike shop where a mechanic cleaned and regreased the bottom bracket, tightened the pedals, plus a few other things. The squeak was not audible on the bike stand, but persisted when I rode the bike.

Eventually the mechanic noticed that the rear mudguard was slightly out of alignment, and was grazing the wheel!

I've had that problem with several cannondales and have fixed it by using the heaviest grease I can find to regrease the BB threads. Finish Line Ti-Prep usually does the trick.

You could try wrapping the bottom backet threads in teflon tape which is a suggestion I got on a bike that creaked alot. It works sometimes and sometimes it doesn't. The thinking is that the threads on the bottom backet and the threads on the frame have a little play and the thread fills the gap. Threadlock compound was suggested too but I'd try the tape first.

Make sure your wheel is set in your dropouts correctly. I own a Cannondale road bike & it is very, very fincacky in this regard. I dread taking off the rear wheel since it always takes me no end of fooling around to stop the squeaking...

i have an aluminium mtb which had a really annoying squeak that was driving me crazy ... it would squeak when you were putting power on the pedals ... i did everything you have done, pulled everything to bits, regreased everything and rebuilt the bike ... it still squeaked so i tightened every single bolt to within stripping point and it was still there ... finally figured it out to be the saddle squeaking ...
