When I bought my o-ring I think it said lifetime on there some where, which brought out the cynical snort, but it is one of the best things I ever put on. I think back then it was $45 compared to a $17 or $18 standard chain. Over 20 years on there but 10 were in storage and I only adjust it when I need tires. Compare that to making an adjustment at least 3 times a summer.
What do you use for lube on the chain?
