I had 5 King hubs in my fleet just before selling my old bike a few years back. I borrowed my buddy's king tool and gave them all a birthday. What a waste of time! One set was from 2001 and had seen AM duties mostly one set on my DH bike dates to 2008 and the lonely rear hub was a second hand DH from a young guy on the Australian Junior DH team. It had sure seen some mileage and wasn't as nice inside but boy was it still smooth! I could rebuild hubs all day long with that thing. It's just an absolute pleasure to use!
I'm running Project 321's on my Slayer now (love them!) and occasionally miss the angry bee but i love the almost -silence just as much.
