Experience with ZTTO ULT (Steel Cogs, Alloy Spider) Cassette?

[geramonta]

I've been reading a little bit about these cassettes and have any of you tried the rubber gasket kit that Sram sells to help with the noise they create?
You mentioned that it's due to resonance so it might be a good think to try.
I've added the image of the kit, I believe you should be good with buying a O-ring kit with several sizes as well and trying with that by the way.

I was looking on AliExpress but couldn’t find anything specific. However, if someone has it and can take some measurements, we might be able to look into buying a set of O-rings or something similar to try it out.

I think I read on the weightweenies forum that those gaskets don't do much...

my experience was that the tolerances are kind of poor and as a result the spacing between cogs is inconsistent. This means that it shifts well on part of the cassette, and like garbage elsewhere, no matter how you adjust/trim your RD. I sent two of them back despite them looking great and having impressive weights. Almost great. I hope they nail their tolerances and QC in their next gen.

Yeah, I gave up on mine and went with the cheap Goldix. There's a weight penalty of 70g or so and it has alu cogs but the shifting is night and day from the ztto. Its still a little loud, but it doesn't hunt for shifts anywhere.
At some point I'll pony up for the expensive ultralight version.

As to the rubber rings, they're lipstick on a pig.

I have the Goldix all steel ultralight hub in 12sp 11-34. I have the same experience as above with the Ztto cassettes. Cog 5 is the noisiest and it gets better on either side until you are cross chained which is understandable. Shifting is more of a clunk and you have this resonating sound mentioned above. I can live with this as long as there is longevity.
