Thank you for sharing this here. And for doing this study. Am reading now.

Taking a break to suggest you have a nearby resource. Ron Boi of RRB Cycles, Kenilworth, has built a lot of unusual and extraordinary wheels for a very long time. Assisted by his degreed mechanical engineer older brother, Wally. Thirty-five years ago he was building 12-spoke wheels for Lon Haldeman (6'4", over 200#, originator of Race Across AMerica). Those were built from Ambrosio rims taller and heavier and stronger than was common at the time but still well under 500 grams and no one would see them as tall currently. Maybe 20mm tall. Also built quite a few 20 spoke racing wheels with Scheeren rims at about 10mm tall and 200-240 grams, as insubstantial a rim as could be imagined. They worked.
