in another forum someone said that eggbeater can rub against the bottom of the noise and if it is carbon fiber like mine, it can make a crackling noise.
So I checked the bottom of my shoes. Sure enough there are some good scuff marks wearing into the bottom about where the pedal would hit.
Right shoe
Left shoe
That same person also told me that Crank bro has a product called shoe shields
Has anyone here had a similar experience? Or tried the shoe shields?
Oh and I listened carefully this morning and it is happening on the other set of pedals on my commuter bike. My commute is pretty flat and generally I take it pretty easy, so never heard it on the commute until I went hard and was listening for it.
