This Black Knight Ion Element PSX double pack contains two high-quality squash rackets that have been developed with David Palmer. The beam is slimmer and the head-light racket uses Black Knight’s latest technology to increase its aerodynamic performance. Stiffness, control and balance for hard hitters are delivered by the Nano-Crystalline and Thermal Core technology. The thin PowerNick 19 strings also reduce air resistance and provide excellent power. The rackets come supplied without protective covers.
