A track cog obviously has to be threaded on tightly and the lock ring as well. Maybe the mechanics don't get that and they are only hand tightening the cog, thus allowing it to develop some play between the hub and lockring..that could eventually strip the hub. I have two sets of Surly hubs and they have both worked flawlessly with nothing ever slipping or stripping whatsoever despite the fact that I skid, skip and what not and I weigh over 200 pounds.
Agreed. I think a lot of the people bought the hubs and installed it themselves. Thus the strippage.
From what I can tell, the Surly hubs look fine. It just so happens that there was a number of complaints.
I think maybe the learning threshhold + loose cog play might be a factor.
