Hello hello!:ciao: I have a question, doing around maybe 20-50 mph I can hear kind of an odd sound from my front wheel. I don't know how to describe it exactly, maybe kind of a whine? Pronounced at above 4k or so I believe. Any ideas on what that might be or does anyone else notice a sound like that on their bike? I looked at the pads and I don't think they're rubbing against the rotor or anything like that. I was trying to think of what other moving parts are up there and couldn't come up with much more.. any help?
