Anyone seen something like this before? i tried to undo the cog and in doing so the entire hub including threads started turning, on both side of the hub. There do appear to be some sort of notches for a lockring tool on this side. Can't tell if it is meant to do this or if it's fucked. When I turned it, the metal plates around the hub started bending apart.
Correct answer. Not all that surprising for something made under the Soviet regime (not that Russian industry has improved that much in the succeeding quarter of a century)
Just messaged the guy I bought it from, he says it's intentional. He says that by spinning the hub you can increase or decrease the tension of the Kevlar
