Size for size solid will always be stiffer than tube - pound for pound tube will always be stiffer than solid

In general tube is stiffer than solid, second rule of area, something like that... years since I went to school.
I believe the issue is when you start putting bends in it that things fall apart.

This any good?
From my copy of Staniforth. He doesnt suggest any particular starting point for diameters but does say allow enough space in your bearing blocks to go
up or down in dia. depending on the result.

I've always assumed that anti roll bars were made from spring steel.

Jambo, this is exactly what I would be quoting aswell...
the solid is double (in some cases) the stiffer of the two, however for most practial purposes the TUBE is stiffer (by weight) than the bar - you just
have to plan your takeoff points very carefully!
