SR 11 12-25 cassette squeeking under load issue

Hi there, has any owner with SR11 experienced any squeeking noise under load while the chain is on the 4-6 gear cluster? This is the smaller 3 gear cluster, the larger cluster gears or smaller indvidual gears doens't make any noise.

The squeaking can happen with moderate load on a hill climb. What should I check for? The rings are definitely in the right place. I have thoroughly confirmed it. Is it a matter of greasing?

A shot of spray lube in the area of the rivets would provide a quick answer. I've never read of such a problem and I read a lot of Campy postings.

The only creaks I've ever had while climb were from a rear skewer that needed lube and tightening. I'd be curious to know how you've isolated the noise to the cassette.

Have you torqued the lockring? Maybe the cassette is loose. I've never heard of a cassette squeaking.

Thanks DaveSSS, I isolated the noise by trying different combo. It's consistent with both chain-rings. As soon as I shift into this cluster of gears the creaking noise comes out. Didn't matter if it was on a larger or smaller chain ring.

What's the area of rivets, is that on the cogs?
