Ultegra CS-R800 11 Speed Cassette - Runs Rough
11-34 Ultegra CS-R800 11 Speed Cassette

Ultegra chain and drivetrain. All new-ish. 11 spd freehub and using supplied spacer.

Anyone else have this issue? Noisy in general and rough feeling. Also found another issue doing research where the third largest cog(27) will make a click every revolution. This seems widely referenced on the web. I had not noticed but a quick check reveals this as well.

Anyone with this issue find a solution? It shifts just fine and is not really noticeable except when cleaning chain etc. But now I know...

Different chain? Different cassette? Just shut up and ride?
