I replaced my chain, cassette and middle chainring (the others were not worn), and I still have more chain noise than I would like. Chain is PC-59, Campy 13-28 9 speed cassette, Campy triple crank. I have adjusted the rear der cable tension and the B-tension screw, checked the tightnesss of the cassette lock ring, rd bolt and jockey pulley bolts. Still have a constant noise, like a tinny clacky noise in all gears. I turned the bike over and the noise seems to occur as the chain leaves the upper jockey wheel going to the cassette. But I do not see any bad teeth or excess play in the jockey wheel. Rear der is 1999 Mirage model.
Other than trying a new chain, what else could be wrong? Thanks.

Bent derailleur mount? Bent derailleur? Bent cage? Worn pulleys? Chainline issues; same noise in a middle gear? 'Dry' chain lube?

When my chain is too noisy, I take out my hearing aids.

In my experience, the loudest chain noises occur from centering error of the rear derailleur. Does it occur in all gears, or only some ?? Perhaps you should adjust the derailleur centering to be perfect within the gears that you use most.

Try some more oil, then go through the steps Muzi mentions. You may also have misadjusted your cable tension on the derailleur. Let it go slack, then try again. Sometimes I can get your clacking when the cable tension is too high. -- Jay Beattie.

Hi there.
This sound that you hear would not be the Campy freehub ratcheting would it? I find my Veloce 9 gear freehub to be fairly noisy and 'clacky' is a good description of the sound it makes.

I had a lot of noise when I replaced my chain and cassette. It seemed to be coming from the jockey wheel, so I installed a new set of pulleys, and the noise went away. There was no visible sign of tooth wear. After trying everything else which posters have suggested, you might try replacing the pulleys.

Or taking the present ones off and clean.grease them.

Jay, thanks for the suggestion. I readjusted the cable tension, and the noise is gone!

You're welcome. Glad it worked. -- Jay Beattie.
You people and your "cable tension". Drives me fuggin nuts. The cable tension is based on the spring in the derailleur. When you lengthen the cable path by adjusting either of the barrel adjusters (on der, or downtube) the tension remains basically constant, the position of the derailleur changes.
PLEASE don't say this any more. How about describing it as what the hell it really is, i.e., POSITIONING THE DERAILLEUR PROPERLY!

In the heat of my foaming rant I hit the wrong keys. Anyhoo, if you properly describe what is going on, the readers will understand more clearly the solution and more about their bikes in general.

I agree that is a incorrect description what is happening. It is voodoo bicycle talk from the incrowd. No newbie know WTF it means.
