About 1-2% of the hubs (either sold as hubs or wheelsets) have stripped when using the provided cog. Some of these were also using very low gearing which adds torque to the cog. Some of these were also no doubt somewhat user error with not entirely tightened cogs and lockrings, or some other type of situation.

All of these cases (to my knowledge) were resolved to the customers satisfaction with minimal hassle. No need to send back to me for inspection or anything. A couple digital snapshots, and some email is enough for me. Even though I am convinced at least some of these were user error, I consider it all under the heading "**** happens" and dealt with it in a way that made everyone happy.

My suggestion is that anyone who rides a low gear and/or hard (as in aggressive skids, etc) should certainly get a better cog than the one supplied just to save everyone some grief.
