I have a thoroughly frustrating squeak emanating from the area of my crank/bottom bracket (Campy 10-speed). It's a very loud squeak that occurs erratically. Sometimes it won't squeak for an entire 3 hour ride. The next day it will squeak starting 15 minutes into the ride and continue occasionally throughout the ride. It will squeak a few times and then go away for an hour. It never does it for more than a minute at any given time and the individual squeaks rarely last more than a second. It only squeaks while I'm pedalling and doesn't seem to bear any relationship to speed, cadence, or pedal location. The bottom bracket and crankarm bolts are greased and everything seems to be properly tightened. So, what do y'all think?

Pedals, chainring bolts, cleat bolts. Heck, even "heard" a pair of shoes that had soles that sporatically creaked from the cleat area.

Good luck. :)

Try greasing the seatpost.

You need to feed the mouse on a more regular basis :)

Heaps of thanks the responses so far. However, this squeak is definitely not the seatpost type of squeak. It's a loud high pitched sound that's foreign to me and it squeaks in or out of the saddle. My brain's working overtime thinking of something that sounds similar to describe the noise. I shoulda gone to Mechanic School!
Sure sounds like shoes/cleatsKerry Irons

Take out your cleat bolts, grease them, and reinstall. Spray some silicone or wax lube on your cleats. Try squirting water into your cleats/pedals when the squeaking starts - that will probably tell you if the problem in in that general area.

Sounds like your hub bearings need a shot of grease.

I had something somewhat similar and it ended up being my left Time pedal was not tight by pedal wrench, but appeared tight by hand. One difference though, out of the saddle there was enough pressure that i didn't have a squeak. Make sure your cleats are tight also.

How about a chain squeak? You gotta agree, it is a possibility. Yeah, i think you do need to feed the mouse more often, or it will starve and then you are dead.
