I don't understand how a cheap cog or lockring is stripping threads. I have a $5 cog that I've run on some bontrager wheel and hub for a year, over to a friends weinnman wheel for 6 months, and now I've been running on my dura ace hub for the last 2 years. I've had no issues with it at all.

I have plenty of friends that ran the stock cog that came on their weinnman wheels from an ebay store, no problems. My brother ran his stock cog from one of those real cheap $120 wheels, tubes, tires, cog, freewheel sets off some eaby store, again no issues. I think people are just weak and don't know what tight really is
