Ran the analysis again with a 65mm*1.8mm spine, which yielded 14, 16, 85 % increases to the torsional, lateral, and longitudinal distortions respectfully. The total weight for the frame and sub frame with this thickness, just under 6kg, a roughly 1 pound saving from the initial thickness.

I will sketch up an egli styli frame and see what that gives in terms of rigidity and weight.

I will also see if a sort of tube based wishbone frame can’t be made to work for similar weights.

This idea i could get behind.
Two shots of egli TZ frames, and a Rau cantilever frame. Rau took over from Egli when he called it quits.
