I ran the numbers and it says I need one tooth less on the big ring which is why I'm asking if that will make as big of a difference as that half link. I sure hope not.
Just trying to double-check before buying a new ring.
Yes, that's the calculator.
I think one tooth on the chainring will be about half as much change as adding or removing a half link. There will be about half a tooth difference in the amount of chain touching the chainring.
