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?

You have a fixed free hub and you have the fixed cog on the wrong side.
No way a bb lockring from an old bike will fit the fixed side (smaller diameter).
Yes, the fixed side lock ring will have LH threads.

Well, I could have sworn these wheels were Fixed/Fixed (thought I do have a freewheel on one side a fixed cog on the other). But I guess It's possible I'm wrong.

So I should flip which side has the Fixed and which side has the free? Crap, means I have to go get a freewheel remover tool.

I agree with powers2b. Sounds like you have a bottom-bracket lockring on there. BB lockring and freewheel threading is often the same.

Yes, swap sides. A fixed cog on the free side using a BB lockring is not a good solution (although I've done it using a regular FW hub - but I also used two brakes and did not try to brake with the cranks). Not only do you need a freewheel remover tool, you need a track hub lockring

Yea, that makes sense. Further evidenced that the lockring tool I have was not liking the size of the lockring, probably because there is a difference between the lockring for the hub and the BB.

I am going to the LSB this afternoon, will fix it today. Might also pick up some other little bits.
