Good information for me to ponder. I had a nice set of wheels built with HED Belgium C2s and CX Rays but 32x32 a few years ago. While the wheels were stiff, I felt as though they were a bit too stiff and rode a bit harsh. I had nothing to compare to at the time and it could have just been an inaccurate assessment. 24x28 works well but I am beginning to think that 20x28 and 20x24 will be fine as long as it is a quality build.
