yeah I SS'ed my Centurion... it took me about 2 hours start to finish... used an old threaded hub... I am using a 17T cog, and the 11T as the lockring...

I picked up a 16T BMX freewheel, that I may put on, but I need to wait to get a bigger chain.. those teeth are HUGE, and my wimpy 7 speed chain won't fit on there...
