I just built up a fixed gear(my first build) and I decided to go with left side drive--just for the fun of it. I was wondering that since the wheel now spins the opposite as it would have with right side drive, would there be a problem with the cog unthreading itself? The pressure of pedaling forward is in the unraveling direction. Would the pressure of backpedaling counter it? Or is a lockring and loctite sufficient?
