13 years! :shock: I got two maybe three years outta mine before I had to change 'em! Mind you, I'd done several thousand miles through all the conditions/gloop that our country could throw at us! I jet-wash as well (I know, I know:!) , so that doesn't help things.
10 years! :shock: I take it you don't use the jet-washer then??
I can't help it, it's just so quick and easy with the jetter, and I wash and lube it after every mucky ride. I do spin the wheels and sorta "waft" it over the bearings though.. Still, bearings are so cheap and easy to do that it's not really that much of a problem.
