I frequently ride accompanied by a "chirping" sound as I pedal. Last year I assumed it was dust accumulating around the bottom bracket/crank. I had that cleaned and packed before I began riding this year, so it shouldn't be an issue this early in the season. I'm wondering now if it's one of my cleats/pedals. I found one thread here about lubing Speedplay pedals that recommended White Lightning, and I've read the suggestion elswehere to spray cooking oil on the cleats.

Just out of curiosity, though, does anyone have any specific recommendations for spd pedals/cleats? Has anyone tried PAM?
