Even weirder - I had one of these cassettes on my Anderson for a few hundred miles, maybe a bit more. Swapped it out for an 11-40 for D2R2. Just swapped it back on last night. Before, no clicking, and now it clicks! Same bike and all bits the same.

To the OP: I dont remember the circumstances, but I remember feeling a similar "runs rough" drivetrain a few times. I could feel like some kind of binding through the pedals and there is a kind of droney noise associated with it.

I dont remember what I did to fix it, unfortunately.

So I put it up in the stand and watching carefully could see that there are two teeth on the 27T cog itself, not an adjacent cog, that lift the chain momentarily. I fussed with the cable adjuster and eventually made it stop. Fussy!

my experience with KMC chains is that they're noisy the first 50-100 miles...of course, all my bikes are 10sp, so dunno if 11, but they quiet down after a break-in period. good chain!

I have this cassette on two bikes. In the stand one can see the chain pick up on a tooth in the third largest cog, then taking up a smidgin more tension in the cable makes it go away. Only to re-appear a few hundred miles later, and repeat the
process.

Brand new cassette and chain (chainrings, too).

I can watch it happen in the bike stand right before my eyes.

And, of course, hear it while I'm pedaling.

and it seems the R8000 cassette is unavailable in 11-34 to even replace it.

Probably around 200 miles tops on it...hoping it will just go away (but I've heard that before).

You get the "jump" on the second biggest cog and overall rough feeling always?

With chain 3rd cog down, one link will ride up momentarily on the same tooth (marked with Sharpie) of the 4th cog down.

Happens with big as well as small chainring up front (also new).

Runs fine (smooth and quiet) in all other gears, including the 4th cog down.

Yeah I might try that too. I don't know what the hells going on with these but I almost hit the cogs with a wire wheel to try and "break it in" and then just for got about it.

Pete, I'm running KMC chains, and this happens on my HG800 cassettes, and the solution is always a tad more cable tension.
