Hi: I am enjoying learning to use BikeCad Pro. My goal is to build a frame/frames for personal/hobby use. At this point, I am planning on using steel tubing. Everything I read suggests custom frame builders will take rider weight and bike riding application (e.g. road vs cross) into consideration when choosing a tube set. I have been looking at bike geometrys online gain insight into frame design.
Does anyone have any recommended resources for understanding and choosing tubing diameters/thicknesses based on rider size, weight, intended use, etc? Other than general recommendations (e.g. thin tubing may feel whippy, thick tubing may feel stiff; large riders may need thicker wall tubing, etc).
Thanks for any insights,
