     Is this something different than the normal "bearing space"
    clicking???
    
     I have the same set-up and have that noise during coasting.

    You always go for the easiest, cheapest possibility first.  That
    would have been the bearings.  It sounds as though you've eliminated
    that.  How about the pawls of the cassette?  One of them could have
    a kink--I'm really reaching; I've never heard of that happening, but
    you never know. ;)

    A loose spoke can cause a clicking sound..
    
    	-Mark-

    I have a clicking sound in my front wheel that comes and goes.  
    I have reduced it to the rim/spoke nipples.  Because it does not
    cause a problem, haven't bothered to rebuild the wheels.  
    Wheels are Record with Araya Aero rims.

    I don't know what the answer is, but there are some things you could
    investigate that may point you in the direction of the noise, or at
    least eliminate some possible causes. For example, when does the noise
    occur? While coasting? While breaking? While pedalling hard? ...
    lightly?  Does it get worse while cornering? Cornering left, right, or
    both ways? Is it affected by what gear you are in on the rear mech? ...
    the front mech?

    Is the clicking regular, or random? How often does the click occur?  Is
    it related to the rotation of the wheel? Or the rotation of the pedals? 
    Or the rotation of the chain? (E.g., a click that only occurs once
    every two or three pedal rotations may indicate a dodgy link in the
    chain.)

    I'm not asking you for the answers to all these questions. But if you
    start thinking about these sort of issues, it can often lead you to the
    cause of the noise.

P.S. Moderator? How about changing the title of this topic to something more
descriptive of the problem, e.g. "Bearing noise problem"? Then other people with
similar problems can find it using DIRECTORY/TITLE=BEARING.

Chip,

	As far as I can place this noise it is no different from
	the "normal" bearing space clicking.
	I don't think clicking of bearings is a normal feature.

	And if coasting is riding normally on the road, I also have
	that noise during coasting.

	My Bikeshop mechanic said that he checked those pawls and
	there was nothing wrong with them.

< Ref 2473.3 >

Mark,

	The wheel is at the moment at the bikeshop and they are
	checking the spokes today.
	I let everyone know what the result is.

< Ref 2473.5 >

Les,

	It only occur during pedalling (coasting).
	The clicking is regular.
	I'am going to investigate if it happens every two ore more
	rotations of the chain or pedals.

	I'am going to change the note name in "bearing noise problem"

	I let you all know what eventually the problem was and what
	solution we used.

I had one of those in-spoke reflectors on my front wheel that was loose.  It
made both rubbing and clicking noises but only under stress (i.e. out of the
seat climbing).  It was a bear to find, (I retrued the wheel, adjusted the
bearings, and had my local bike shop do the same), since I was assuming bad 
bearing, bad spokes, etc. etc.   Finally I gave the reflector a yank and surprise;
it wasn't loose enough to move except with a yank, but it was just loose enough 
to make noise as the spokes compressed/decompressed.

Moral.... When the obvious answer isn't right, look for the non-obvious

    "coasting" is "not pedaling" i.e., just rolling along, often
    a preferred method of going downhill.  May be done an aero
    position, but may also be done sitting up tall enjoying the breeze.

 Try coasting and when standing on the pedals lean the bicycle from side to
 side.  If the periodic noise changes --- gets louder or goes away --- it
 is probably a loosening spoke.  This is without any pedaling to eliminate
 other drive-train problems.  If it is a spoke it can be found with a
 tension meter or just tighten up the whole wheel to consistent tension on
 each side for the eight speed wheel dish.
 
 

  I had the same exact problem with the magnet for my computer.  Drove me nuts
  for about six months 'til I figured the damn thing out...

Dear Colleague's,

	Thanks for all the input you have given me.

	We found the solution.

	The tension of the spoke's had to be higher.
	I tested the wheel and didn't hear the clicking
	anymore.

	It is really a big relief for me biking without
	that a annoying sound.

Thanks,
Bert Brummel.

My new road bike (on whose chain skipping problem some of you assisted me)
has a new noise.

Under acceleration (tall ratios), there's a slight clunk-clunk-clunk noise.
I haven't yet correlated it to pedal RPM or wheel RPM but, at ~18 MPH, it
clunks about twice a second.

The store where I bought the bike told me to bring it in for a quick tune-up 
and tightening after things had worn in a bit.  One of the things that they
mentioned was the crankset.  I was on Martha's Vineyard last week so I
couldn't take them up on their offer.  I did, however, visit a bike shop on
the island; once the bike was on a work stand, the noise was shown to come
not from the crankset but from the freewheel area.

Any ideas of things to check?  As with the chain-skip, I'd prefer to learn
how to troubleshoot this stuff myself.

Thanks \ Erik
      

    Check for a bent or broken axle.

    I know this presupposes a feel for frequencies but
    
    If it is related to wheel speed try .-1, if it is related to peddle
    speed try something `up front'.  Otherwise, and my FWIW is to check 
    for a tight link. 
    
    Obviously peddle speed is easy to guess, wheel problems can be guessed 
    at by the `does it go away when you stop peddling test, Wheel speed can
    be judged by braking *gently* and listening for the noise as the
    irregularity in the rim (there is always one) goes past the blocks.

    It's actually more of a ka-dunk ka-dunk ka-dunk than a clunk clunk
    clunk.  It's fairly faint (i.e. someone riding abreast of me can't
    always hear it).
    
    If this helps.      (-:<
