After six months of people complaining about the sound of my hub I finally decided to see if I could quite it down a bit. I called Industry Nine and talked to one of the service techs there. He recommended Dumonde Tech PRO X Freehub Oil for regular service, but if you really wanted it quite you could use the Dumonde Tech PRO X Freehub Grease. So I bought both, but decided to go straight to the grease to see how quite that made it.
