Interesting thought, but i don’t think that’s it. I did use the original bolts. I tried single ring bolts too, but they were actually too short. The original bolts fit fine, and there was enough excess thread that they could still tighten.
The chainrings are just too close to each other, and I’m totally confused as to why.
