Technical data sheet
As expected, the main technical characteristics remain unchanged. In particular, weight, balance and inertia do not change, as well as the string pattern and spacing between the strings. On the other hand, taking into consideration the stiffness of the frame, the company still reports it as 72 RA. While in the previous version this data tended to be sometimes even higher, in the current version it is easier to find some downward deviations. For instance, among the frames we tested, none has exceeded the value of 71 RA. This data is also confirmed by the dynamic rigidity expressed in Hz. Almost all the other data measured by us in the lab perfectly match the data declared by Babolat. The only slightly inconsistent data is the swing weight, which results to be 8 points greater than the declared one, and could be due to some further polarized masses.

The FSI Power system is now a classic for this racket, which basically takes care of the frame-string interaction, exactly as the acronym suggests. While, among the innovations we find the HTR System technology, born to provide additional torsional stability – not that we felt the need for it on a frame like this – but it could have been developed to be combined with a project that also includes the introduction of SWX Pure Feel. The latter is essentially an improvement with respect to the previous Cortex Pure Fell (always “powered by SMAC”), aiming at further dampening the harmful vibrations and thus providing a good impact feeling.
