it's been getting worse lately. at first it was just under load, but now it
is practically all the time. it sounds a little twangy like spokes. could it
be in the hub or b-bracket?

Wheel reflectors can work loose and make irritating twangy noises
like an out-of-tune harp being pluncked.

One time when I thought I was getting bottom bracket noise, it
turned out to be just the cadence sensor got swiveled around,
and the magnet on the crank was hittin' it.

Excellent advice. It took me an embarassingly long time to figure
that was where my buzzing was coming from once. I'm having buzzing
again from there, but it's because the cage is busted. Which I'm
not sure how that really happened. I guess from carrying it up the
stairs into work everyday. My shoulder tends to rub against that
cage, and I guess it didn't like the repeated flexing.

It could be any of those - but it could also be the spoke crossings. I
bring that up as a possibility because of your description of the
noise. It's easy enough to eliminate that as the cause - just a small
drop of oil at each of the crossings, and a light squeeze to get it to
move between the spokes. If that quiets the wheel down, you're done.
If not, your spokes will last 10,000 miles more (though since the life
expectancy is probably in the seven digit range, I wouldn't get too
excited about it).

People get all whiny and self-righteous when they're self-centered so

Oh, be careful! Some of that oil could migrate down through the spoke
nipples, and cause the tube to EXPLODE. TIC

I've always been fond of this explication of it.

I second that.
Highest respect to you Claire... I'd hate to see you disappear from the
forum.

Well, saying you have a rattling noise coming from your bike is rather
vague. Have you tried localizing it? Is it coming from the vicinity of
the wheels (which one)? the crank? Does it have a pattern? what does
this pattern coincide with? is it in time with your pedaling? the turn
of the wheel? etc.

I hed a rattle that almost drove e crazy because nothing seemed to be
causing it. Then one day I reached for my frame pump to fend off a dog,
and lo and behold, as soon as I grabbed it, the rattle vanished! Problem
solved.

yes, as far as i can tell it's either the spokes or the rear cog (or both!),
but it is significantly louder under weight & torque on a bumpy road (which
i cant safely duplicate while putting ear to wheel-hehe there was a day
though!). it does not match the pdeal cadence, it only coincides with
bumpyness. when coasting the noise is more of a rattle but when pedaling
hard it's more like a twangy clicking sound-so ya maybe it's two different
things. as per following post it may be the spoke crossings but i have also
noticed the rear cog seems to rattle a bit. i'm not surprised since
sometimes getting a bike back from the shop i'll find other problems that
weren't there before...btw i did check the bottle holder5 & pump & all other
fasteners...

Did you do the build yourself, or did your LBS (or reasonably fascimile
there of) do it? If the LBS shop did it, maybe you have an 'extra' nipple
or piece of metal in the rim.

ALL the fasteners??

Chainring bolts

Could be your cassette rattling if it is not tight
enough. grab it and wiggle it. Shouldn't wiggle.

Also: that little nut gripping your presta valves can
rattle if it comes loose.

My money's on loose cassette.

thanks for the tip, i tried that and there is less noise. the remaining
sound is likely the cog.
about spoke-life, however, i lost 4 in the first 4K miles and had the wheel
rebuilt...
