I have also had the shoelace making noise.

I had a noise last year. I thought it was a pedal. Swapped them for others I had. Nope. I checked the cassette, thought it was loose, and retorqued it. Nope. It was minor. I recently tightened the chainwheel bolts, so far no noise... We'll see.

Another guy on the forum had a noise, and after checking everything, he figured it out, after riding a different bike I believe. It was his knee.
