8 and 9 speed chains were skipping pretty bad on the SS Rip, so I had to use a big KMC single speed chain. Which mostly works. Except for the pins on the quick link, which stick out too far, and run into my tensioner:
I was getting a noise and occasional skip when the pins hit the tensioner cage.
Since I just need a tiny bit more clearance, I cut a channel into the tensioner:
Which somehow made things worse. I guess I have a sharp edge somewhere. Back to the dremel.
