Yea, I mean't speed related. When I speed up and slow down in the same gear, the noise speeds up and slows down. Also, the noise is not constant. Kinda hard to explain, but it's like you can hear the noise only during a certain part of the wheel revolution. For fear of sounding like an idiot, it goes something like this: grind....grind....grind....grind
, only during a certain point in the wheel revolution. Ok, you can get up off the floor now
