Chain and Chainring life
I've heard different things. I've heard that a new chain on old chainrings will cause the chain to die quicker. I've heard 2,000 miles for a new chain. I've heard once a season the chain (how many miles, I don't know). When the teeth look worn (for chainrings).
Take a look at the rings. If they look low/worn, then get new ones. If they are still looking fresh, I'd say keep em. I got NEW rings (53/39, FSA) on ebay for $60. I probably saved $25-30. Check the ebay stores, they have new stuff at some good prices, just keep your eyes open.
I keep track of all my equipment and find that a drivetrain is pretty much good for a very long time >100km IF you maintain it and change the chain basically every 20k km. Just my experience

I've been wondering the same thing. Mainly because when I shift into the big ring my chain sometimes pops and it's got me scared that I'm going to snap my chain. Is it every 20,000 km (20k km) that you say you replace your chain, BBB? I looked over mine tonight and it doesn't look like its got alot of wear and tear (the bike has ~2000mi on it). Should I see if I need a replacement?

I opted for a new chain after a year, one of the links wouldnt manuever smoothly and would pop on my chainrings. Even after cleaning the hell out of it, and greasing it up. My LBS said "Your chain is like an oil change on your car". Much better ;p.

for the chain... get a chain wear indicator THIS ONE IS BY PARK TOOL
For the chainrings.. look at them and watch them for thinning of the teeth, then eventually look for cupping on the right side of the tooth (it'll begin to wear down to a sharp point - like a wave breaking) you can see it pretty well without the chain on the bike.
here is the thinning (first step)
this is the wave shape (second step)

Man this post really has me worried. I don't think I have taken very good care of my bike. I have taken my bike into the shop for its warrenty visit, but other than that haven't done much (except replaced a tire). My bike has almost 3,000 miles on it. What sould I consider replacing?

just take it to the shop and have them look it over.. (they have the chain wear indicator tool and can look over the chainrings, cassette, cables, break pads, and derailleurs for you)

Hey... that tire thread got me thinking.... about how long is the life on a chain and chainrings? I definately need to replace my chain at this point, but how long can i go with the rings? THX
