I've gone through many bikes, and many chains in my cycling life, but it seem to me that the Shimano Dura Ace 9000 11 speed chain wears out faster than other chains I've used. I know 11 speed chains are narrower, but does that mean shorter chain life? Those who have experience with all kinds of chains, do you find this particular one needs to be replaced more often? How about with regards to other 11 speed chains? Also, this is the only chain that "lets me know" when it needs to be replaced. It will start squeaking, even after lubricating. It gets worse and worse the longer it goes without being lubed, but after a certain time period, the chain starts squeaking almost uncontrollably. For most of my other chains I just wait until my chain checker is at 0.75mm, but wouldn't ever get any squeaking noises. Maybe I'm just expecting too much out of it...
