Help w/ annoying noise . . .morrison

When I am out of the saddle, I hear a very audible noise coming from my front wheel. It happens w/ any noticeable lateral movement of the frame; particularly on the down-stroke. It seems to alternate from side to side, and sounds like "vvvvvvvvvt" (pause) "vvvvvvvt" (pause), etc.

At first I thought it was just the brake pad rubbing against the rim. I have eliminated that possibility. Also, the wheel is true.

FYI, I am riding Velomax Circuits. One thing I noticed is the valve stem is the smooth type that is not threaded to the wheel. Could this be the reason? Also, (and this might sound silly) if I tap on the quick release with the wheel engaged, there is a barely perceptible rattle.

Any thoughts?

I hadn't considered that (not surprising given that I usually need help pumping gas on the self serve island). If that were the case, though, wouldn't the sound be on one side only?

Well, you hear it...

Isn't it simply added friction from standing? Did you try changing tire pressure a bit to see if it changes the noise at all? Do you hear the noise at effort or simply because you stand, like at any given speed?

I'd trouble-shoot trying to isolate variables... See what I mean? What influences the noise level/frequence/etc.
At effort, but only when I'm standing. (thanks for help) nmmorrison

Are you absolutely sure it is not the pads? Have you ridden with the front brake quick released (Carefully of course)?

In my case it was brake rub from a true wheel due to lateral wheel flex. Bought new stiffer wheels (better local hand built set) and problem solved.

Try riding a spare wheel set. Then with the brake disengaged for that set as well.

Also consider that sometimes new tires make a funny noise when sprinting and cornering causes the side to come in contact with the ground.

Good luck bro.

Cheers!
