So what happened here?
I had just resurrected my Miyata 110 fixed gear. The bike had laid unused due to a poor choice of bars and having had a few parts removed for other bikes.
So I get on for a test ride and things are going well. I stand up and give it some torque and the cranks collapse under me. I barely regain control of the bike and they slip again. I quickly realize what had happened. My cog had slipped.
Depressed and dejected, I walk the bike back to my garage, thinking that my flip-flop hub will no longer flip nor flop anymore. Sad because one of my planned uses for this bike was for windy days and I was going to run two cogs with as big of a tooth difference as I could fit.
Anyway, I get home and remove the Dura Ace 16t cog, only to find that the threads on the hub looked as good as new. So did threads in the cog. No play or nothing.
So I rotofixed it back on and got the lockring real tight (which I know it wasn't before, but I have brakes and use them so I didn't think it was a big deal to go around the block with a not so tight lockring.)
What's the deal? How could the cog slip without stripping the hub? I've ridden the bike around town a few times thus far and had no problems with this wheel.
