Frank, stop showing your engineering inability. Did I not talk about
the Octalink BB? Is that the same diameter? And since you seem to
think that mild steel and Chrome Moly have the same torsional strength
why do they make drive shafts on high performance cars out of chrome
moly instead of mild steal since the cost difference is 200%? They do
no increase the diameters.

It would help if you quoted the stuff you're objecting to. Frank's
point, if I understood it correctly, was that strength != stiffness.
Chalo commented on a lack of stiffness in some obsolete bottom bracket
format or another, not a lack of strength.

I believe Frank would say that CrMo and mild steel have approximately
the same stiffness, and also that he would be right.

Correct.

I don't think Tom understands the difference between strength and
stiffness. And as usual, he's misstating my points in general.
