I wondered if anyone would follow up and ask that. He took the advice of the LBS mechanic on it. Honestly, I was a bit suspicious and thought they were probably OK. But my friend is not the kind of guy who replaces his chain more than every 2 2 years or so. He may have run the chainrings down by having a chain way past its prime?
