So this question may be stupid, but I have an unsymmetric Surly lockring and am wondering what direction it goes on. One end has a smaller shoulder than the other. The larger end has the divets for use of a lockring tool. This isn't the one on Surly's website now. Does the larger or smaller end lay flat with the cog? The "Surly" logo shows when the smaller end if pressing against the cog, but it seems more intuitive to have the larger end with the divets for the lockring tool against it for ease of installation/removal.

Make fun of me as you may, provided you let me know what's right.

The protrusion inserts under the cog to allow the lockring to have more lockring threads (as opposed to cog threads) to grip on. But note you do not need to use this protruded side, you can opt for the flat side as the protrusion may not be necessary (or on rare case, incompatible as the protrusion make the lockring incapable of ... locking).

Oh and another thing. Don't abusive with it. You can leave embarrassing scratches on the ring with the lockring tool. I screwed up and left huge indentations on the divets. My scared-up Surly lockring works perfectly but clearly display my noob-ness. Heh.
