Along the blank of any rod in action, compressive and tensile stresses coexist, which normal carbon fibers can cope with very well. When torsion occurs, the carbon tubular can fail. Torsion causes: fractures, inaccuracy in casting, reduction in distance due to misalignment of the rings, loss of power due to the disorderly transmission of force along the shaft. With X45 technology the fibers that wrap the stem are arranged diagonally and bi-directionally, and force it to work correctly. X45X (Full Shield) is the latest and most advanced evolution of X45 technology which allows you to have blanks that are even more powerful, resistant and with better casting performance. The transfer of energy along the shaft is in fact 25% more efficient, while structural rigidity and resistance to torsion improve further.
