Calfee makes a beautiful bamboo bike. Im hopeing to use FEA (finite element analysis) to construct the most effiecient frame possible and in order to do that I need to find all the stresses regularly put on a road frame I was just wondering if anyone had links to sites that discussed such topics. I will be doing a static force analysis on the frame in order to determine the optimal sizes of the tubing necisary to build the lightest safest frame with optimal flexing properties.
