I was just thinking back to the discussion a couple months back about compact geometry. People kept crowing about "smaller triangles" being orders of magnitude stiffer. So here's my question. When you have roadies constantly in search of ultimate stiffness and carbon construction bringing the weight of a bike down well under UCI regs - why are modern race bikes not all mixtes? Not only are the triangles WAY smaller than even a compact frame, there's an extra one......
