• how a different size chainring would make a difference?

    When the chain is derailed from the big chainring, it needs to land correctly on the teeth of the small chainring (and vice versa).

  • I found a good example that show your explanation below.

    Show how the teeth is line up almost precisely when shifting from small to big.

    If the teeth Is a little further forward or backward, it can “slip” until it hook into the chainring, this happen with mixing chainring.

  • That makes sense. I guess I could also try to rotate the smaller ring to get the teeth line up better. There are 5 possible combinations. So I guess one should work. I will order the new ring and report back.

    Thanks everyone!
