Can I put a single speed freewheel on a fixed gear only track hub? Anybody have experience doing this?

Thanks,

Mr_macgee


PS: On the Sheldon Brown's website, it says I can but I've never heard of this before.

"Any standard track hub can also be used with a single-speed freewheel just by leaving the lockring off. The thread is the same. Sometimes people worry because the hub thread isn't as deep as a freewheel specific hub, but this is never a problem with a single-speed freewheel."
