Most people will also tell you that you will not find a lockring on a 'freewheel' because while one is used to secure a 'freehub' to a wheel, 'freewheels' are threaded on so there is no need for one. That is why this particular unit is unique because it uses a lockring to secure the cogs to the racheting body but it is in fact a thread-on freewheel from an older bike. Hope this clears things up for you
