Interesting site. Make differences between bars more salient (eg: width ranging from 400mm up to 810mm; backsweep from 0 up to 80(!!) degrees; rise from 0 up to 100mm).

I understand the basic argument wrt width (wider -> more control; wider -> less aero). I kinda understand the backsweep argument (not enough or too much puts strain on the wrists). I don't understand why one would want a rise instead of a proper stem. And there is no discussion on the merits of aero extensions (from experience, I know that I have tried to ride in this position over butterfly bars, quickly giving up because it was so uncomfortable)
