The Wilson Hyper Hammer 145 Squash Racket features a Hyper Carbon construction that creates ultra stiffness in an ultra light frame for maximum manoeuvrability & power. The Wilson Hammer system contributes to the ultra light construction creating a head heavy balance that is perfect for creating increased power to compliment the manoeuvrability. Power Holes, uniquely designed oversized string holes allow for greater compression in the string bed, resulting in a significantly larger sweet spot which increases power even further & results in a much more forgiving frame. Hyper Hammer technology, combined with the Hyper Carbon frame, produces a very stiff racket, contributing toward power with the added benefits of superb stability. Features a 497 cm. sq headsize, lightweight 145 g. frame & a head heavy balance.
