Ok I have at least 6800 miles on my 11 speed Shimano Ultegra chain. I keep it pretty good take it off after maybe 1000-1500 miles and soak in OMS and such. I don't ride in the rain at least on purpose. The cornfields of Illinois are flat so no real climbs. I measured my chain with machinist rule shows less than 1/16 or close in 1 foot.

I just think keep riding it the bike shifts flawless. But then maybe another voice says, no just put a new chain on they don't last that long something must be amuck. No skipping and I am not a slow rider I general run 50 mile routes at 17-19.5 mph, I no kid at 58, but can chains last that long? Finally I notice I am running Conti GP4000's II and they have 6000 miles on them and not worn out yet.

So would you all put a new chain on I don't see any wear on cassette? I normally get 5K on chains but wow this has me thinking.


BTW the 57 miles this morning even early were brutally hot here. I have drank at least 5 liters of liquid in some form or another and not even had a beer yet....that is coming soon.

Good gosh Lou how fast do you ride and how old are you? I have to admit I am runner first but last 5 years have decided my running legs are gone but still go very slow. On the bike though I can keep up with fellows 1/2 my age..
