I went over to my L.B.S. and asked the young guy behind the counter if he could swap some cogs from one freewheel to another (I brought them for him to see).
He told me that freewheels sprockets are "integral" and there-fore not removeable.
I told him they were threaded. He looked at me without responding. I left.
Do you ever feel like you are in the Twilight Zone?
