Ah. Yeah. Gotta remove the dork disc.D Griff wrote: ↑Thu Feb 13, 2020 10:47 amIt was from the rear derailleur... it had one of those plastic discs to prevent the chain from going too far inboard and it was all dry rotted, cracked, and rubbing as the wheel turned so I ripped it off. I just need to be careful shifting down back there. It has suicide shifters that are continuous rather than clicking, but the shifting is actually really smooth and nice.
If it overshot the biggest cog on the back, you can adjust the limit screws on the rear derailleur to prevent it from moving that far. Should have (2) phillips head screws on it, for high and low limit points.
