What is torsional flexibility (torque)?
Torsional flexibility refers to the shaft’s flex around its axis. Torsional flexibility should be considered when fitting flex, and matched in a consistent fashion. Generally, the lower the shaft torsional flexibility, the stiffer the shaft will feel. Too little torsional flex results in a very stiff feeling shaft that won’t load completely. Too much torsional flex will cause the shaft to feel soft and can cause timing-related control problems. Steel shafts range between 1.5 and 3.5 in torsional stiffness and better graphite shafts range between 1.6 and 5.
