Not to say it isn't admirable to try to quantify this stuff, but bamboo is a natural material. There is a range of wall thickness and quality in the average bundle. If you used only half of the best of it, you would probably be around an industry average for rods. Rods are highly stressed, and you can't make a good one without Tonkin cane of good quality. But people have made bikes out of any old junk they found at the garden center and the furniture mart. So I don't think they are all using high end stuff. Or grading the good stuff that hard if they are. All that really leaves is the tube size, which is easy to scale from existing bike pictures. Not a complex project.
