I was looking at the wheels on Ritchey's site and noticed that most of there wheels come with a larger non-drive flange than drive flange. According to Ritchey the "hi-lo rear hub flange eliminates dish tension problems." How can this be? If you work out the geometry a smaller flange should even out tension because of the smaller bracing angle (assuming the spokes aren't tangential to the flange). I have also spoken to the people at Phil Wood who have the same design. They also claim that a larger non-drive flange will even spoke tension and that the fact that you can use the same length spoke on both sides is a coincidence. Does anyone understand the logic behind this theory? If so please enlighten me.
