When I started again, I went through the whole bike, of course. The chainrings looked great. Two years later they were shot. I ride 3-5 days per week, averaging maybe 150 miles per week. Is that about the normal wear rate?
These things are, of course, relatively cheap, readily available, and very easy to replace. I probably shouldn't worry about it. Seems to me, though, that I could buy a set of steel chainrings and not worry about it literally for the rest of my life. As an aside, it's a little distressing that I'm thinking about things like this in those terms...

Depending on the year, almost all of the later (after 90ish) shimano have shifting ramps on their rings for better shifting. They work.
If you are wearing front ring, that's means you are working, getting in shape. Buying a new ring is a great thing
