Its really more like a creaking sound. Every time I really torque the cranks, during trackstands, stopping and starting; its really bad when I reverse the direction I am applying force. Just a creak sound and a tube resonating that creak. I just really hear it then, and at the bottom of the pedal stroke.

I checked out the pedals and cranks. I tightened the cranks, but they seemed really tight already. I changed out my pedals, but nothing changed.
