Thank you, everyone for your thoughts. It is good to learn to read this.
You must keep them lubed well for the small amount of wear showing......
Actually... hmmm... I'd like to say that I am very good at keeping this stuff clean and lubed... alas that is not completely true.
I lube and clean the chain and the rear sprocket about every 600-1000 miles and have been known to go to Colorado and back without doing it at all (so about 2300 miles). When I clean it I soak with wd40 first, then wipe down and soak again if needed (all while on the bike). Then I dry it and spray on some Teflon spray lube. That's pretty much it. I then feel good about myself and go ride. And perhaps do it again in 500-1000 miles but I don't keep close track.
Exception is if I ride gravel or rain, then I do it all soon after coming back, mostly before next ride.
I dunno, I keep reading those threads about the Zen of chain maintenance and never quite get what the big deal is as it seems to last 25k with a little more than a lick and a promise?
Front sprocket I did not even see yet. I assume it is still there?
But then again even in this thread people say that their stuff wears much sooner so possibly my next sprocket/chain kit will be the Kryptonite for my way of doing it.
