Or you could go for extenders with rubber sleave like the Silca ones.

Just a piece of tape is probably the most common. Just cut a piece and poke it right over the valve, letting the valve tear the hole then tape it to the rim. Easy peasy.
That's not making sense to me. The little bit of a jingle comes from the top of the valve stem (inner side of the rim). If I poke the valve through some tape and then insert it into the rim I'm not seeing how the tape will travel up to the top/inner part of the rim.

1415chris - I don't use extenders. I have 80mm valves / Michelin tubes on 50mm rims which is a decent fit.

(BTW, it's a very minor jingle so it doesn't really drive me crazy or anything.)

You put a piece of tape over the valve when the tube is already mounted. You’re not trying to build a cushion between the valve stem and the inner diameter of the rim valve hole at this point, you’re just basically taping it down to the rim in order to keep it from banging against the sides. The tape ends up on the external sides of the rim around the valve. Yes it’s visible. And yes it stops the clicking. Done quite often.

FWIW, I've been suffering C64 clickling/creaking and have had a couple of mechanics do everything they can do to play whack a mole. Broke down and got Ceramic Speed BB and will get it installed tonight. Hope this works.

I Agree.

Not sure if you looked into the chain ring bolts. A friend had a click and we swapped cranks and the noise went away. Put it back on and it was there again. Re did all the chain ring bolts with anti seize and some grease and that got rid of the click.

What crankset are you using?

Ive now put Loctite on the Campy BB cups. It went away and has now come back. Ive also changed the rear QR skewer. I really dont want to have to buy a Ceramic Speed BB especially when the SR cranks already have ceramic bearings. Im wondering if its an issue with 12 speed Campy chainset with the UT bolt now only accessible from the NDS. The noise usually starts after about an hour of riding and is intermittent. Ive checked the chainring bolts and the rear drop out.

I did the same thing with new Campy BB cups and creak still came back. Instantly no creak with Ceramic Speed/Colnago BB. Been totally silent for about 3-4 weeks now. I've got SR EPS v4, including mid crankset and internal interface.

Are the Campy bearings removed off the spindles to use this BB?

But then you’re paying a whole lot for some Ceramic Speed bearings that you don’t even use, and imo aren’t as good as the CULT bearings on SR. There’s no way I would opt for the Ceramic Speed BB over the standard Campy Cups for 86.5x41, at a cost of about $40.
At this point I’d probably have to be there to diagnose where the click is coming from, and wish I could be. Those are the jobs I actually like, the ones that seem to stump people, especially when it’s been to several shops without resolution.

@wilwil: what loctite did you use, and when you say you used it on the Campy cups, I’m assuming you mean between the Campy cups that were pressed into the Threadfit cups. But didn’t you say earlier that the Colnago Threadfit cups were loose at some point. Did you remove those, apply loctite (if so, which one), then reinstall and torque properly?
Really hard to do this over the Internet.

I apologize, but I was wrong. My bikeguy said we did remove the Campy bearings off of the spindle to use with the CS BB. In any event, I found the CS BB online from a UK shop on sale at a great price; so, I didn't mind one bit paying up to get something that solved my creaking issues.

I’ve checked the Colnago threaded frame cups and they’re tight. I used medium strength stick Loctite. I can’t really see why Loctite can work as it’s designed for threads, but thought worth a try. I never had a noisy BB on the C60 with post 2015 Campy 11s. I agree with you about spending £200 on Ceramic Speed. I’m really wondering how the CS is installed with push fit UT. The only video I can find is for CS using threaded UT cups where they simply change the bearings. The CS cups have bearings in them that’s why I’m puzzled.
