I suspect the same thing comes into play with tubes in a bike frame. However there is not a tool designed for bike tubes to find the neutral bend plane which would result in a more supple ride as opposed to a more stiff frame build. It is something that has me wondering about the way we build bike frames, and if there could be more design concepts involved like using spring constant methods and positioning of neutral bend planes in tubes opposed to strong planes in the tubes for ride design. I'm pretty sure I am talking in an unfamiliar way for many here but it may be difference in the way frames perform. Contact me offline for more info if interested. Smiles, MH
