Wow, pretty bad! I know that's not my problem (if the brakes were rubbing I'd definitely hear it, and the wheels spin freely). That said, that did cross my mind that day as there's a sound that was coming from my front wheel it seemed on each revolution--thought it might be brakes but when I spun the wheel around I didn't get the sound and it spun fine. Still not sure what the sound was--any ideas? Or could it have something to do with the brakes and it only does it when I'm riding as opposed to just spinning the wheel?
