The other day thanks to the "fixed/free hub" thread I discovered that fixed and free cogs had the same threading. Before, LBS's had always seemed pretty convinced that a free cog had to go on a free thread etc. I have a fixed/free ENO hub. I have put a 16t on the fixed side with a lockring to give me 75 inches for the road and a 14t on the other side, suicide; sans lock ring, to give 86 inches for the track. Is this the right way round, is there anything I can put on the suicide side to make it a bit safer?
