surly cogs have a bit of a narrower shoulder, leaving plenty of threads for the lock ring to grab onto.
This is what I feel to be the problem upon close examination. As it has spun off again, the bike is hung in the garage for inaction (no working brakes.. so it's not useful) until I can get back to the not so local shop where I got the wheel.
A little dissapointed.
But, I've got other bike to ride.
