Hi,

I have a flip flop track hub on my fixie with a 17 tooth fixed cog on one side, and 17 tooth freewheel on the other side. Was thinking about taking the freewheel off and putting a 18 tooth fixed cog on the other side. Will this work? I don't want to ride a suicide hub, but am not sure if there are lockring threads on the freewheel side. Domost flip flop track hubs allow this?
