Yeah, by money is on a bent hanger. Doesn't take much, and the symptoms are just as you describe.

CycloSpirit Derailleur Hanger Alignment Gauge https://www.amazon.com/dp/B077SZBZKY...ing=UTF8&psc=1
It's not so much that the hanger is not straight, as much as just aligning the drivetrain. IMO anyways. Does that make sense? |

I really don’t think so. After taking it off and laying it flat, there was no play. I replaced it anyway to eliminate that possibility. Will be a good back up I guess.
The rest of the drivetrain is new aside from the chain, chain ring and shifter. SRAM GX derailleur and GX cassette both 11-speed (non-eagle) and should be compatible with other NX stuff I already had. Dropped a link in the chain as the GX cassette has one less tooth in highest gear. |

I've nursed beat up derails along by playing with the b tension screw and increasing the distance between the upper pulley wheel and cassette to give the chain more room for error, however it has side effects like slow shifting and occasionally having to over shift a touch to downshift a gear. Not sure how SRAM 11spd would react to that. |

I know that Eagle stuff is really touchy about derailleur alignment (and just about everything else in the setup).
I had trouble tuning my xo setup. I was on the road and took it into a shop, where they diagnosed a bent derailleur hanger. They straightened it. Ran fine after that. I ordered a new hanger and straightened it before I put it into my toolbox. Yes, it was off a fraction. But that fraction is enough to cause plenty of frustration. Now I know I can just replace the hanger and be GTG. |

When you said this, it finally clicked. I’m almost certain it’s a bent frame or at least a bent rear triangle.
My drivetrain was having shifting issues after my fall (mis-shifting, dropping gears when pedaling backwards, etc.). This is what drove me to start replacing the cheap things like the derailleur and hanger when troubleshooting. The same issues are present with the new parts that existed with the old. The impact hit that side of the bike and it would make sense why I can’t dial this **** in. I’ll know more on Tuesday and report back. |

I tried the "string test" by tying a piece of string to the rear axle hole on one side, running it around the headtube, and tying it to the opposite side axle hole. Then measured the distance from the string to the seat tube on either side. It's out of alignment by over 1/4".
This seems like the culprit. I'll confirm when I take it in tomorrow. Might be time to test that Santa Cruz warranty/customer service. No-fault replacement at least. |

Verdict is in and..LBS says it is a "twisted" derailleur. How I don't know. The derailleur itself looks like-new but the tech believes that that's why the dude on Pinkbike was selling it. They tried to bend the jockey cage to get it back in alignment but ultimately couldn't get it right. I dunno. If you eyeball it looks straight but I guess its twisted or something. They tested the hanger and it was perfectly straight. Frame inspection also didn't lead them to think the frame was bent.
Brand new 1x11 GX is on the way for now. Cheap solution hopefully. They complimented my wheel build. |

My Mukluk came with Microshift Advent X, and I complained here about it being ****. Well, I am proclaiming that it is not as ****ty as I originally thought and that the bike builder just did not bother to fine tune the setup. After removing the cable from the derail, properly adjusting the limits (the shifter has its own, non adjustable low limit it seems) and then re-adjusting the cable tension it shifts quite well. The clutch is still inferior to the Shimano and Sram friction only design, but when cranked down on the clutch pivot, it works well enough most of the time. A coarse toothed pawl type clutch is just not a good idea to limit movement all of the time. |

This was probably my last ride of the season. Most stream crossings (on Mountain Lion) were iced over. Only maybe a 20' section of ice on the actual trail, though, on the section that usually has a bit of running water.
New tire day, too. |

I did notice that when in the lowest gear and I pedal backwards, the chain drops several gears and binds up. From what I'm reading this is normal but I've never experienced this on trail. Does this happen to anyone else's 1x? Never thought about how much I pedal backwards even just to position my feet. |

Is the replacement a different model than the original? Clutch tight enough? |

This happens to me however it seems to be more frequent if the chain is on the hair shorter side. |
