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.
