Anyway, I took the bike to the LBS the other day because I'd heard the drive train creak a few times, and figured it must be time to replace the chain. Well, it's not. The chain wear tool says it's about halfway through its life. ( They took the cranks apart, cleaned and greased them, and the creak went away. ) So, with some lube every 100 miles or so, it looks like I should get 2,500 to 3,000 miles out of this 10-speed chain. I've been getting about 1,000 to 1,500 out of the 9-speed chains on my CX bike. I'm impressed!
Anyone else notice the same thing?
I got about 1800 out of my last SRAM 1091R. It starting stretching very quickly towards the end of its life. But I subject it to the nastiest of the weather around here and live right next to Cougar Mtn. I just got home from a 45 mile(+) ride in this downpour.
I'm climbing 2300 feet on average, per ride, 4-5 times a week...
FWIW, I had a new 10 speed Dura-Ace chain last me 44 miles the week before last.

It broke while climbing on Zoo Hill during the 26% grade part. Fail..
