The Graphite Design Tour AD UB is the second shaft from Graphite Design to use Torayca ® M40X pre-preg. Torayca ® M40X has both high strength and does not deform when loaded. Tensile Modulus is the mechanical property the relates force to deformation. The material in the UB does not elongate when loaded. In a golf shaft, the energy applied is not lost to elongation. It is stored in the shaft and theoretically is released at impact resulting in higher ball speeds.
