Ah, yes. Skipping teeth when we pushed hard. (The Rear Admiral didn't like that.) We didn't have to push very hard and it was getting worse. I measured the chain. 12 inches covered just a bit more than 11 links!
Surprisingly, the new SRAM PC870 chain fresh out of the box was 56 outer links plus Quick Link, exactly the same as what the bike had. I expected it to be longer, with a few "extra" links I'd have to remove.
We don't use the granny ring all that much, which is why it looks okay.
