If you don't count the bike from the co op for the wife that I haven't paid for yet, I did just get some new BB bearings! Hopefully that will take care of the creaking...the same day I got the new bearings I also got a new crankset for my commuter. Hopefully that will stop the squealing (the spindle was separating from the drive side arm - with a GXP crankset/bb. Nothing that can be done about it but replacing it). Hopefully that will be two drivetrains that run quiet and smooth now.
