Just to echo that that is already said, the Art of Wheel Building, has been and invaluable asset to my bike literature. I too built my first wheel and then with the confidence when to try my hand at a rear fixed, it is in it's third season, while one I bought from the LBS got trashed.
I got in a discussion with my LPS babe about my fixed gear building, as she was of the opinion I had built the weel wrong, due to it's asymmitry(?). I put forth the thought that since the wheel had to preform as a flip flop I had to build it with the drive side on both sides of the wheel. She looked at it and finally concurred. i haven't tried to build a freewheel rear. I do want to try a radial, none crossed front wheel. With the weight I carry, a radial wheel would taco, at least I am afraid it would.
