This is just me stating my own opinion about my experiences, and I can easily get 20k miles on a chain and have gone over 30k on OEM chains on liter bikes before there were X-ring sealed links, but I feel like both @shinfo
and @tary preisser
are over cleaning and over lubing your chains which account for the short lifespan.
I could very much be wrong, and I’m not 100% sure the chain is @shinfo
’s issue but I “clean” my chain when it’s warm with a rag and some WD-40 if it’s hugely gunked up or if I have been riding in the rain and can see crap on it, which is maybe once or twice a season, and lube after which entails spinning it with my hand on a stand and dripping a bit on the inside of the rollers until it’s made a revolution or two then grabbing a clean rag and spreading it out to all over the links. Once it’s no longer dry, it’s good. I spin the wheel a few more times, wait five minutes or so and wipe off the excess. I lube maybe every 1000 miles, maybe, and clean only when needed and my small can of PJ-1 Blue is like 10 years old and not even half gone with 3 bikes in the garage.
I feel things like a chain cleaner and a grunge brush can do more harm than good and can cause premature failure as how does the spray cleaner know what’s old chain lube and what’s good chain grease? The rings can keep some lube in but it can be cleaned out or crap forced in if it’s over done.
Like I said, I don’t know it as a for-sure thing, but it seems like a lot of people who clean their chains religiously get a shorter life than I experience. The chain on the ‘11 Triumph Sprint GT I bought this summer was junk in under 14,000 miles because the P.O. did NOTHING to it in that time so there is a level of keeping it clean and lubed you need to do.
Hope you find the issue!!!
