The Tecnifibre Carboflex 135 S Basaltex Multiaxial double pack contains two new lightweight squash rackets with body-built shafts. Their graphite & Basaltex Multiaxial construction enhances the feel while reducing undesirable vibrations. The generous 77.5in 2 (500cm 2) head adds to your power, & the evenly-balanced racquets use the Iso Sharp Design XL technology to stiffen the frame & improve the swing speed. The latter is further enhanced by the detachable Custom Fit Bumper, tested by the great Mohamed El Shorbagy. The frames are supplied strung with a synthetic gut string in a 14x 18 pattern, & include a full-length ventilated cover.
