Of late my Tour Easy has developed a squeak at the pedal-go-round rate. It has Performance Bike Campus pedals, with SPD cleats on one side and a rat-trap surface on the other, and only the SPD side squeaked.
Turns out that the two little mounting screws holding the cleat dingus worked their way loose.
I should probably ease some lube under that plate, just to be sure, but the simple fix worked fine…
(And, yeah, I should clean it, just once, to see what it’s like, right?)
