Just to be anal let me point out two (very) small errors. First, the large BAT bar is 13/16� or 20.6mm diameter, not 21mm.
And second, IF ATI makes any â??Aussieâ? bars they will be using 15/16â? or 23.8mm diameter stock, not 22.3mm as you listed.



Great point about the BAT bar.

The 22.3mm-22.4mm part about the "Aussie" bar is its "effective rigidity" being as it's "hollow" and not solid.

Being as the BAT bar is actually only a 20.6mm then a 22.3-22.4mm bar is roughly twice as rigid comparatively. (IIRC - Certainly someone will dig out their list of formulas and whip up an exact percentage)
