Ran across a front wheel today that fits a 21 inch rim. The strange thing about it is that it looks like a TT brake drum on it. Unless some one put it on a front wheel for a different purpose, I do not know. Can the hub be changed to a car hub? also are the bearings the same as car bearings? this one only has the races.
Dennis, it could have been set up for an aftermarket four wheel brake. Some one posted pics of such a kit a while back. KB
