About three days ago I started noticing a squeak (definitely hadnít been there the previous day) that seems to be somewhere in the drive train (only seems to squeak while the pedals and gears are in rotation maybe every 5-6 strokes..) Iíve lubed the chain, checked the derailleur, and even took it in to the local store. They werenít able to find anything while it was on the stand. I also thought about my shoe cleats since Iíve heard Look cleats are notorious for causing squeaks. However, it sounds more like a metal on metal type of squeak. I havenít been able to isolate the location of the noise (front or back). Any other ideas on what to check before finding a way to live with it?
