The Sonic Core Evolution 130 squash racket double pack contains two advanced frames that ensure an optimal combination of control and power to perform at peak level on the court. The racquet features the lead Sonic Core technology which ensures increased face stability to create more comfortable playability and added control. Additionally, it is equipped with a 490cm (76in2) head with a hybrid-style throat section, plus the length of the frame is slightly extended to provide added reach and easier power generation. Each racquet is evenly balanced and arrives pre-strung with Iconic pro AF (1.25mm) string which adds a tad more power and durability.
