It's on and off, on and off, I don't really get it, but yeah sounds pretty much like what you mentioned, maybe that's something similar? I have biopace oval chainring, could it contribute to that issue? And what is the way to deal with it?


I will have to figure it out once a 15mm wrench is delivered. I have 3 piece crankset for sure, bolts on both sides.
