Thanks, SportsCarDesigner and Cheapracer. These are helpful. The .049 chart is particularly revealing. Thinner wall, larger section = less weight, less twist; I knew the concept, but the figures are impressive.


its how they do it with aluminium bicycles i came here looking to ask why people dont use round tubes in their builds , is it a skills thing (i built a lot of bicycles so dont really struggle) we designed chassis at ginetta and they were all round tube except the g50 which was square furniture tube
