I'm using the same cog as before, its steel, just not sure who makes it..
I once used a cheap cog/lockring combo on a Formula hub and stripped the hub on the first ride. I looked closely at my replacement DA cog/lockring compared to the cheapie and found that the threads on the cheapie weren't tall enough to make good contact with the threads on the hub. It was almost like they were cast instead of cut, they were that bad! And to make matters worse, the ebayer who sold me the hub also sold me the cog, and they should have known better than to peddle(!) such garbage. Needless to say they blamed my install and refused to replace the hub gratis.
Bottom line: NEVER skimp on a cog/lockring set with aluminum hubs.
