Is there any book on how to build a 70cm frame with reasonable geometry and elasticity? Would extrapolations from a philosophy for "normal" frames possibly suffice or would one need to go back to 1st principles and hope?
Were there OT butted tubesets that could build a 70cm frame or would it have been necessary to use straight guage pipes? I'd personally be a little intimidated by the prospect of drawing up a frame for which so little empirical data must have been available to any given frame builder.
