I HATE it when people turn their bikes upside down...for any reason.

Sorry to disappoint. Do you have any advice to add regarding the noise?

That bike of yours looks lovely and shiny!

If you can manage it, I think a video would really help.

...have you tried a new replacement cassette yet ? Any noise problem is usually addressed in a series of steps, with the easiest and cheapest ones done first.
Then you proceed along the most likely avenues. Three of us have suggested this to you as the next step. The rest is up to you.

When I put off waxing my chains longer than I should I get that same noise, especially on my Fuji with newer 105 drive train and especially in the 52/11 cruising. Sounds like grinding gravel and the shifting isn't optimum. It gets so loud I can hear it over my earbuds and feel it through my feet. I'll wax the chain and everything is right again. From your posts though I get the impression you do regular maintenance so that probably isn't the problem. Good luck

A new Ultegra cassette is around $110 now. It is not even in the top 5 cheapest things I could try here, if we're being totally honest.

Funny you say that. For years, I've been using a big bottle of Finish Line gold ceramic lube, which was relatively quiet and smooth to shift, but impossibly messy. I'd clean everything, apply the lube, and a mile down the road on the first ride the chain and cassette would be sludged over black. I actually have transitioned to Rock N Roll lube of late, and it did get louder using it (I need to find something else), but the lube is not the source of the noise alone.

...if we're going to get all honest, Ultegra level cassettes are way overpriced. Maybe you need to go on Amazon and shop around ? I can buy an 11 speed SRAM 11-32 for sixty bucks. I can get one even cheaper if I go with something like Sunrace. But hey, good luck with your repair.

$116 for an 11-30 on Amazon. 11-30 is actually tough to find period right now. When I last bought a cassette, about mid-2020, I think it was around $65-70. Everything's up but our income...

...will a Sunrace 11 cog cassette really not work in your setup ? I've always found them to be Shimano compatible in every application I've tried one in, but admittedly I'm not a big fan of more speeds are better. So I don't run anything with 11 in the back. I forget the Shimano recommended changeout intervals, but isn't it something like every other chain swap ? And isn't 7 or 8,000 miles about average life expectancy for one of their cogsets ?

Iíve said this previously, but do you know anyone who can do a couple minute wheel swap or cassette swap with you?
Just donít shift into the highest gear in case the sir limit position is different (so that you donít dump the chain into their DS spokes).
