Adaptive Tuning Kit Instinct

The Head Adaptive Tuning Kit also you to customize your Graphene Touch Instinct Adaptive tennis racquets to your preference. You can choose between the more open 16×16 string pattern if you’re looking for massive spin, or you can take a more traditional approach and keep the 16×19 grommets in.  Not only can you select the string pattern, but you can select between lightweight and heavy grommets to help increase the stability of the racquet. The kit also comes with handle spacers that allow you to extend the racquet in 5mm increments (5mm, 10mm, or 15mm).  The last feature of the kit is a weighted butt cap insert that allows you to add 10 grams of weight to the tail-end of the racquet.
