My track frame (which pretty much lives on rollers) is Spirit throughout but standard Keirin/traditional sized tubes. It's quite stiff for a steel track frame. That^ should be in a different league.
As I understand... road bikes aim for stiffer DTs than TTs (I'm sure you're aware of this).
Ah. They are massive diameter tubes!
