Anyone have some experiance with chain durability? Going back over the last few years I've used only shimano chains, and I wouldn't mind trying some alternatives.
On the 9 speed all-weather commuter style bike it was HG 53/73/93 (tiagra/105/ultegra and MTB equiv) which all seemed quite similar in terms of life in my use, 3000-5000 kms in mix of conditions. I though that was OK enough.
On my 10-speed roadie I was using ultergra and getting some 6000~8000 per chain. My most recent chain is durace and after 5000 strech is below .75% so tracking along OK. This bike isn't ridden in the wet or dirt very much, mostly kept pretty dry and clean. I'm happy with these mileages.
Now I have a 10 speed all weather commuter type bike. 1st chain (105) did about 2500kms before exceeded 0.75%, where I usually change. 2nd chain (also 105) is 4000 because I didn't realise I had done so many kms and was well over 1%. Most recent chain was the same durace as my roadie with a new casette. Checked it this morning, is at .75% after 2000kms. 2000kms!! I'm not doing a durace chain every 2000, I'll stick with 105s if that is all I can get.
Anyway, I realise the bike gets wet and dirty a lot, but wouldn't mind something that would do a few more than 2000 kms. Even in winter 2000kms can be less than 1 month for me. Any suggestions?
I've always like KMC X10 chains. Just the basic 73 or 93 versions. They don't often get a long life on the CX and MTB due to the dust around here but they should serve you well if you want to try something different. Roadie has an X8 but hasn't been used much in the last couple of years...
Ours is not to reason why...merely to point and giggle
My bike (flat bar, 105 groupset, 2 chainwheels, 10 cogs on the back) just got 9,400KMs out of the KMC chain it came with. We'll see how we go with the replacement, I change both chain and cassette at the same time, but I am pretty impressed. My next chain, on order, is also a KMC. They seem pretty durable and shift well.

While on ten speed I ran KMC X10L chains and binned them at 7-8000km, while they were still welll below .75 (I hate replacing cassettes, you can do a lot of chains for the price of a SRAM Red cassette). I found KMC chains measured .0 - .025 new. Currently have a SRAM Red 22 chain which measured around .05 new, seems to be wearing okay but will probably swap to KMC X11L next time.
Only bad thing I found were mates using cheap 8 speed KMC chains- 3000km and wrecked!
After my experience with my KMC S1 singlespeed chain (so far) and the ~3500km I've got on a KMC x10 on my racer, I'm starting to move into the KMC camp. Previously I was all Shimano but I've had two 105 chains go to rust at the first sign of moisture. The latest had two particular incidents that rapidly brought on rust. First was getting caught in a substantial downpour and having to ride 30 minutes on a road so wet that at times my rims were submerged. I did not immediately dry and lube the chain after, it was rusted by afternoon. The second was a marginally wet morning and leaving my bike in the bike locker at work, had developed more rust by the end of my shift. The KMC x10 has encountered more incidents of a similar or worse nature but still shines up as good as new, it's had more than 3 times the distance on it and looks to be wearing in at a slower rate.
