Head has a habit, a good one I think, of designing unique tennis racquets. That design thrust is seen in the Head Cross Bow series of racquets.
The ‘Cross Bow” is a separate component that fits into the racquet shaft and is secured by an elastomer of some sort which also acts as a vibration damper. As you can see there is a built in “damper” around the two center main strings. In some cases these were removed as being unnecessary.
This Cross Bow model is very stiff, at a RDC flex of 72, but the stiffness is mitigated by all the design features. Holding this racquet belies the size of the head and the width of the beam. It actually feels pretty good.
On the shaft you can see the small metallic bars that act as a vibration interrupter. As you look at the side you can see the various grommet systems Head used to maximize the “slippiness” of the strings on the grommets.
