opinions on loctite and/or rotafix
I've searched plenty and understand rotaxing and such, I was just wondering on what you guys think.
In the past I have unthreaded my cog/lockring skidding (for fun, I have a front brake) and I can't weld the cog on. I was wondering if either rotafixing the cog or loctiting it or both would hold it on strong enough to skid again without worrying about the cog.
Thanks,
J

Unthreading a lockring skidding? Should be pretty hard to do, as it is reverse threaded. Get a lockring tool. Rotafix your cog, and then tighten that lockring down. don't bother with locktite, and don't be a ***** about tightening your drivetrain!

I wasn't the one who tightened the cog when it was put on, it was a shop but thanks for the advice.

I tighten my cog by riding up the biggest hill I can find, or by using the Rotafix method. Then I use a Park Tools HCW 17 to tighten the lockring down. No Loctite needed here.

The guy at the shop said backpedaling and skidding over time can do that, do you think he was covering his @ss? the cog did come off a few days after having the shop install a new cog.

Here's the right way:
- Grease the threads for the cog and lockring (optional, but I always do it.)
- Thread on the cog by hand, making sure not to cross thread it.
- Tighten the cog. My preferred method is to lightly rotafix it on, because you can get it pretty tight with not much effort.
- Thread on the lockring by hand for the same reason as above.
- Tighten the lockring with an appropriate tool. (I use a hammer and flat bladed screwdriver because I don't have the right tool. But that's the Wrong Way so I can't recommend it.)

definitely. The cog should not come loose from skidding, or "over time." it wasn't installed correctly. The dude was either lying or he doesn't know what he's doing. I would not go back to that shop.

Rotafix and Locktite are terribly bad ideas. They can be a pain in the butt to "undo" and at worst, permanently set the cog to the hub or even damage it.
Learn how to properly use a lockring and a lockring tool.

thanks for the responses. I personally don't think loctite is difficult to undo with proper tools and I will definitely make sure everything is tight and properly fastened.

What is the rotafix method?

It doesn't matter how tight I get my cog and lockring on or who does it my **** always loosens up after a couple of months. I'm pretty sure it has alot to do with quality of the hub cog and lock ring... Or the fact that I'm a bad mother****er.

Yeah, a guy brought me his wheel to get the lockring off. It took some drastic measures to get it off, and thank goodness it was a Dura Ace lockring. That thing is made of some really hard steel.
Someone give me a little boost and tell me what the rotafix method is. I've seen the rotofix sprocket now, but is that all it is? The video showed how it's useful for getting your lockring off or on. Does it have a use beyond that?
