This racket is built for power in a lightweight frame. It fuses a lighter hoop with a more flexible shaft for increased manoeuvrability, while retaining tremendous amounts of power.BLX is the new Wilson racket technology engineered with BASALT fibres combining proprietary frame, grommet & grip technologies for a perfect feel. BLX allows Wilson, to fine tune the composition, geometry, grommets & grip of each racket to maximize the feel for each player type. All is left is for the stringer or retailer to customize the right string & tension to meet the customer type of play. The High Tension frame technology creates a double tube construction at key points in the racket hoop, providing extra durability & frame integrity, allowing for higher sting tensions, a larger sweet spot & a cleaner performance.
