I have Mavic Krsyium wheels and hubs. Yesterday, a sporadic noise occurred that sounded like a tire rubbing against the brake. I would also think that if the tire was rubbing enough to make a noise this loud, it wouldn't be spinning at all. Regardless, I looked at both wheels and didn't see any rubbing. In fact, I released the brakes a bit, just to take this possibility out of the equation.
The noise happened again a few miles up the road. I released the quick release and reinstalled the front wheel. I did this because this was the only thing I touched on the bike that day. I didn't experience the noise in the last two or three miles. Does this sound like the source of the noise or has anyone experienced this type of moise?

Take out the front wheel and turn it around.

Mysterious noise always come from Loose saddle or are Crank related----You may be the exception.

Check that the wheel is true and that the tyre is properly located. If it occured more on cornering than in a straight line it could be wheel flex- Loose QR. or bearings loose.

After I performed some maintenance on my driven train recently, I noticed a rubbing noise and for a while could not locate it.

Turns out it was the small length of cable above the front derailleur rubbing on the rear tire. I bent the cable a little, and the noise went away.

Check the rear hub. Had a rubbery squeak on my MTB. Turns out, there was a rubber flange on the non-drive side of the rear hub, and some dirt had gotten in between the rubber and the metal of the hub. A little clean up, and a touch of silicon grease, and the noise disappeared.
