this is terrifying....
Oh, and it doesn't work. Or rather it works just fine till you need to stop really hard.
and then you will, real hard.

I guess if you never put back pressure on your pedals, the lockring is not necessary.

that's all it is, making your chain and bb shell into a chainwhip.

I use this method with a lockring. The latest time that I put them on, I used anti-seize instead of grease, because one cog simply WOULD NOT come off. Couldn't reverse the process, two wrenches with a chainwhip and a cheater bar, NOTHING...
Eventually we put it in a vice with this little tool that was like two metal blocks with pins coming out the top that went into the teeth of the cog to secure it. Then two of us were able to (eventually) use the wheel for leverage to get it off.
So yeah, the lockring would have been unnesseary. But I still use one...

Next week I'll post a thread that I invented a kind of bicycle that can stop without the use of brakes...
Then the week after that, I'll post that I discovered a wonderful new trick of standing still on the bike. I will call it crank-stand...
Oh, and it does work wothout a lockring. Otherwise half of Italy would be dead by now.

I don't use a lockring on my colnago. I have a lockring but the first time I rode these hubs I was at the track. When I tried to change my cog it just wouldn't budge even rotafixing it didn't work and I used all the methods hereNT did (except the one he used to get the cog off) but nothing so I just put a bigger chainring on and have ridden ever since without the lockring. I'll put a lockring on once I finally get that cog off.

His physics are a bit off. He says that the force is applied at the outer rim diameter instead of the cog diameter. The force is actually applied at the diameter of the outermost wrap of chain. The more times you can wrap the chain around the cog, the more you can tighten the cog. The rim just works like a cheater bar.

The point is that this is a bad idea, we all know it is a bad idea and yet it is being promoted by a slick website, thus gaining credibility among those who don't know any better. This is happening more and more often.
Yes, a cog will stick if applied dry and cranked down hard (another bad idea), the point of a lock ring is to make sure that when friction is overcome by force, there is something to hold it in place.
Despite your constant existence in the grace of St. Jude, some things are simply a bad idea even if done regularly without problems. He (GP) is a track racer, and isn't as worried about stopping as going.
How many italians ride track bikes?
Italy is one of the big places for high end bikes but the same is true for cars, that doesn't mean everyone drives a Lambourghini.

"you only need to have a problem once, then you will appreciate using a lockring"
sounds like my argument for brakes.
18 years without a lockring.

isn't there a hub somewhere that the rear cog bolts on instead of threading? THAT would make lockrings useless if it ever took off.
