The Head Speed 135 double pack includes two squash rackets made specifically for powerful back-court players. The rackets are made from Auxetic material ensuring more touch and a softer feel and guarantee improved playability thanks to Octagonal Power technology in the shaft. Added power and increased swing speed are delivered by an oversized 78in2 (500cm2) head and Stringbed X-tension technology. The frames weigh 135g (4.8oz) and have a head light balance for easy manoeuvrability. To let players choose between a 12x17 and 16x17 string pattern to either enhance power potential or optimise shot control, there is innovative Adaptive Fan Pattern (AFP) technology. Plus, the rackets are strung with an arm-friendly Reflex 18 string.
