So this may just me being stoopid, however...

If I understand it correctly, the lockring on a fixed gear, is supposed to thread the opposite way the cog does.

However, if I recall correctly, my Lock ring threads on the same direction as the cog does?

I have a soma fixed/fixed track hub a dura-ace 15t cog and a lockring I found in my garage from an older bike.

Are there different types of lock-rings? If it is supposed to thread on the opposite way, then why was I able to spin it on?

Is it that they make lock rings threaded for putting on old bike hubs that aren't designed for fixies?
