How to remove a stubborn lockring

andrewleitch86 So I've got a lockring that I need to remove. I've tried a lockring removal tool and also the screwdriver hammer technique. It loos like it's been put on with no grease so it's probably seized on. It's a new Fuji Track so it's a Formula hub. I know about the thread stripping with Formula hubs so I'll be careful with the new cog.

Make sure you are turning it the right way, it loosens/unscrews clockwise as you look at it.
