I'm not sure that the Loctite is really necessary if you do a good job of tightening the carrier, I just wanted to be 100% sure. The lockring would still do its job if the carrier happened get loose and start to unscrew, but that is not good for either the hub or lockring threads. In any event, every time you install and remove a normal screw-on cog you are wearing out the hub threads, whereas with this system there is no wear no matter how often you change a cog.
