An excellent summary of the problem and solution.

I might add that frequently the chain stretches over time and begins to chew
into the side of the chainring teeth. It also chews into the teeth of the
rear cassette (the cluster of rings on the back wheel). So if you replace
the chainrings, the old chain may give poor performance - grinding, chain
suck and such. I found that I had to replace them as a set on my bike.

Luckily I had a newer cassette to replace my old one on the back wheel.
Otherwise the new chain probably would have had bad shifting and skipping on
the rear cassette. Hope this doesn't happen to you, but be aware that if
the new crankset causes noise in the rear of your drive train, that's likely
the cause.

Cheers
Gary
