The Aldila Limited Edition Rogue Black shafts employ ‘Graphitic Carbon’ with a modulus of 110 MSI (million pounds per square inch). The modulus of the graphite material used in typical graphite shafts ranges from 33 MSI to 55 MSI. By incorporating this new material, Aldila is able to make the shaft stiffer and lower torque without adding weight. At the same time, the placement of the material in top third of the shaft (grip end) allows the shaft manufacturer to slightly counterbalance the shaft to work well with today’s heavier driver heads and the longer length of modern drivers.
