XeneCore is a new fiber technology that uses high-pressure solids to form and reinforce the graphite fiber composite to incredible levels of strength that has allowed Donnay designers to reduce the thickness of the racquet beam width to a dramatic 15 millimeters, the thinnest in tennis. The thin beams greatly reduce air resistance (the same reason that sleek sports cars outperform bulky SUVs in wind-tunnel tests) providing unparalleled levels of maneuverability. The high-tensile strength of XeneCore also dampens vibration and provides unexpected power, while reducing the "shadow effect" from the beam blocking a portion of the string bed on off-center hits resulting in "frame shots." The net result of XeneCore technology is a previously unachievable level of all-around performance.
Hexagonal molding is a manufacturing process that incorporates 10 hexagonally shaped string holes on each side of the racquet frame during the molding process. The X-Series Black, Blue and Dark Red models use this technology that allows tournament-level players to generate maximum spin due to increased torsional rigidity, resulting in a firmer feel. The hexagonal holes also make the racquets play slightly stiffer than their RA (machine) ratings that provides exceptional power.
|Customized Weighting Technology System Kit|
The Donnay customization kit that is sold separately allows users the option to adjust the weights and balances exactly to their liking to any Donnay racquet. There are three interchangeable buttcaps weighing two, seven and 12 grams, along with weighted slides that can be easily applied to the sides and top of the frame in the blink of a changeover. The combination of the slides and lightest buttcap tips the balance more to the head for more power; no slides and the heaviest buttcap increase control and further enhance maneuverability. There are 10 combinations in between.
