I was thinking that it used a multi speed freewheel. I had seen the bike this wheel was on, and it had a multi speed freewheel installed. I was eyeing this wheel for a while, then I saw it sitting in a corner today. I got it for about the same price of a meal at a fast food joint. His reason for selling, was it is too crazy.

When I get this wheel going, I can either save it for when I start track racing, or ride it VERY carefully on the street.

One more question. The bike that it was on had a rear brake. Can I use a brake on this wheel?
