Anyone else having issues with the Drive Ring chipping and cracking. Have had the hub for 3 years now with bearing change in hub shell once a year. I check play in the axel every few months. Lost engagement in the hub on a ride, upon disassembly I found three significant chips in the Drive Ring. I thought maybe I could have the ring replaced, no go. needs a whole new shell with threaded drive ring pre-installed. I contacted I9, basically, I'm out of luck, and should have bought a 350 instead. Is three years typical for Drive Rings? I am not a heavy Rider, so I was surprised to see this. Pretty Expensive lesson learned.
