Of course, I do replace them before they are streched (Park CC-3 tool (which is VERY conservative on when to replace the chain -- measure max distance between the pins on the tool with a digital micrometer and you'll see what I mean)). I don't ride in the rain/mud. I use ProLink Gold lube ~every 250 miles. I've read that with this kind of maintenance I can expect to get THREE chains for each time I'll need to replace my sprockets (~ 18,000 - 20,000 miles) and ONE sprocket wear replacement for a chainring(s) replacement (~40,000 miles/perhaps ~50,000 miles for the big ring). Your mileage may vary ;) I’ve been getting 6,000+ miles on my Ultegra 9 speed chains.
