Help me diagnose a wheel issue

jwalther · #1 10-23-2017, 06:59 AM

My regular wheels are Campagnolo Eurus, with Shimano hub body. The rear wheel has developed an intermittent rhythmic "tick." I've run the wheels on different frames, using different cassettes, so the issue appears to be with the wheel itself. My LBS inspected the wheel, cleaned the hub and pronounced it fixed. The noise returned, and the wheel was sent to Campagnolo for service. I understand the hub was rebuilt and spokes retensioned at the service center. Still ticking. . .

Any thoughts? I've invested in excess of $125 trying to fix the problem and am not keen on throwing good money after bad.

Valve stem ?

Skewer....I realize it could be a lot of things....but had same issue not so long ago with a Zonda wheel.....everyone had their theories....but as soon as I changed out the stock skewer for a older Record one....tick went away.

Try a little dab of boiled linseed oil where the nipps enter the rim and where the spokes enter the hub...Also the QR and valve stem, like mentioned above.

And...while you are checking above items.....I've had same noise from a popular Quick Link also. It wasn't a KMC or SRAM.

Good point, pedaling or coasting? I’ve had a noisy KMC 11s link...

Thanks for the replies all. I've tried different tubes, tires, and skewers, and the wheels were moved from one bike to another so not a chain issue either. I'll try some linseed oil and see if that does the trick.

You might try to identify an offending spoke/nipple by weighting the rear wheel (rest an elbow on the saddle and put as much of your weight through it as possible) and rolling the bike backwards and forwards slowly.

Drop of oil at the spoke crossings and on the dropouts.

Good luck!

I am with angry here, sounds like a valve stem thing (even though I only have seen this happen on deep carbon wheels).

Dont just change the tube, maybe take the valve stem down.

It is strange that it has been worked on twice and still there. Would rule out hub for me so either valve stem or spokes.

people mentioning KMC chain, he said the click is on other bikes as well when he brings the wheels over so unless he also bringing the KMC chain, its probably not the chain.

also, this is annoying and you just can't ride with it/will obsesses until you fix it

Does the tick tick tick get after the faster you go?
Go away completely when you go faster?

It would be really odd, but it could be the joining block. super common on Mavic. But never know.
