Thanks for the information vomitron! You said to check the skin, what exactly does that mean? The glue bead where the hub meets the wheel?

Since I got this wheel for only 10$, I am going to ride it on the street. It is going to be a "go fast" wheel. I can either use it on my fixie, or a LeTour I am working on. Using them on the fixie might not be too good, since you say the threads are fragile. First I have to figure out the whole tubular deal. They are expensive!
