I have 2 Pure Drives (2015). One is about 2 years old and the other is a few months old. The older one is pretty beat. Both are approximately the same weight
I tend to restring them at the same time with the same string, tension, machine etc (Alpha with Wise)
For some reason the String Bed Stiffness (DT) of the newer one measures consistently 1-2 (kp/cm?) higher than the older one using a Beers ERT)
Does anyone have any theories why? Could the frame on the old one be "softened" up? I've noticed this the last 4 times I've restrung them. They definitely feel different when playing.
