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? Last edited by charliedid; 06-13-2019 at 07:51 AM. |

what do you mean?
It rides fine on the road with no issues but you hear something when cleaning? Is the bike upside down when you clean the chain?

which rear derailleur, what size bike?
that video did not show the person adjusting anything while turning the cranks. seems like a chain line or cable tension adjust issue...or a defect .

Yeah I'm convinced it's some manufacturing issue. What I want to know is do I need a new chain or a new cassette? |

Chain
I would try a new chain- But I did have an 8000 cassette that had a bad cog. Mine was 3rd one down from the 34, so 27?
Never ran right on multiple bikes with different chains. Shimano warrantied it and gave me a new cassette. |

I guess I could press them on it. Which cassette did they give in replacement a newer run of the same? |

If I had to just jump right in I'd try a KMC chain first. Have you had the issue or know that a non Shimano chain works?
I wonder if this has anything to do with this cassette being able to run on both 10 and 11 speed FHB? Who knows. |

You mean HG800 right? The 11 speed 11-34 that can fit a 9-11 speed MTB hub or 11 speed road hub? I get a bit of this too, known issue. Did Shimano ever deal with it? Are new ones better?

I personally use a SRAM 1170 with a 105 level 11-32 11s cassette and it is quieter and smoother than the Ultegra chain it replaced. Maybe that was just a bad chain, but it was noisy and broke at three different links on a short tour, whereas the two KMC quick links held fine. |
