P Moore asked: "what besides tubing stiffness might make a main triangle
stiff or stable?"
Frame size: small frames are stiffer than large frames.

And yet that very light 531 normal gauge 1973 Motobecane frame handled heavy
rear loads (all comparisons on Tubus Fly racks) better than much stouter
frames. Why should that have been?
To turn that into another question: what besides tubing stiffness might make a
main triangle stiff or stable?
It was rather remarkable: That presumably thinnish-wall, and certainly lighter,
normal gauge 531 Motobecane handled rear loads better (for me -- this is all
judged by seat-of-pants feel -- than that (for me) overbuilt 2003 Curt
frameset, and better than with the Ram.
Fond memory: grunting 45 lb on the rear Fly in a 67" fixed gear on that
Motobecane up an uber-steep 4/10 mile hill at 4 mph by the bike computer --
yep, 20 rpm.

Hi Patrick, on the rear load thing - that stability is in the main triangle.
