What merits chain replacement?
What would justify replacing the chain on a bike? I honestly never thought about it before as a part that wears out, at least not on a bike.
I have an older bike, and I have no idea how many miles are on it. All I know is that I've put 1000 on it. What should I look for to indicate that the chain is worn out?

Chain stretch, or the elongation of the chain due to wear. See Sheldon's article and how to determine the stretch of your chain towards the bottom of the article.
As the chain elongates, it abnoramlly wears the rear cogs (and the front chainrings to a lesser extent) to match the chain. All is fine, until you replace with a new chain, and now the cogs and chain don't mesh properly.

greater than 3/32" beyond 12" for 32 pins is when I replace mine. the new one will show an alarmingly fast rate of wear initially but it will slow once the chain and cogs have meshed properly (as previously stated)

the gist of it is if the chain has "stretched" (elongated) a small amount, you replace it. If it has elongated too much you probably will have to replace the rear cogs as well.

Thanks for all the info. That was a great article. A bit later today i'm going to go measure my chain and see where I'm at. If it's over 1/8 over, I'll run it until summer, when I'll get a new chain and sprockets.
