What noise?! you have to be kidding me! That noise is called a CHAIN going over a COG, you WILL hear something. You are not flying a ******** "Meet the Jetsons" space capsule! even that piece of futuristic crap makes a sound.

Put the camera down, step out of the basement and please do all of us a favor and ride your f^^king bike, then magically your noise may disappear. Its called wear and tear, its good for a bike.
