Is this guy stupid or a troll?
FFS... You have a brake can you just chill out? I'm riding on a hub that I received with no idea if it was rotafixed, locktited, or what, and it has no lockring, and I'm brakeless.
Here's your safety chart:
Torqueing real hard with a chain whip (only recommended on velodrome) #4
(that's just my estimation anyway)
combine them as you wish, the safety compounds, but so does the difficulty of removal. Locktite+rotafix=you may never get it off. I have no experience with this, but my brain tells me if a rotafix can take two big guys to wrench it off, imagine rotafix plus something that's already hard to undo.
Has anyone heard of a rotafix coming off? I haven't, but I have heard a number of cases of locktite coming off.
If your hub takes a lockring, just do it. Get it over with, you'll feel safer and they're less than $10.
