Just unveiled by Wilson Racquet Sports, the [K]Factor tennis racquet is the newest evolution in tennis technology. The highest level of technology available combines four new proprietary Wilson technologies the in the [K]Factor to bring you enhanced control. Building on the nanotechnology platform that began with Wilson's top selling nCode line, the [K]Factor picks up where the Wilson nCode nSixOne Tour 90 left off.

The [K]Factor has been specially engineered for Roger Federer to maintain his dominance, while improving his all-surface game. The new industrial design innovation that improves handling, maneuverability and provides additional feel was directly inspired by the #1 in the world Roger Federer.Federer states, "The [K] Six.One gives me incredible feel! With [K]Factor, Wilson has taken racket technology to a whole new level and I love what [K]Factor does for the control of my game." Federer switched over to the [K] Six.One Tour at the Australian Open, where he swept the Men's Championship without dropping a single set.

[K]Factor now brings racquet technologies to the next level by introducing Karophite Black, a breakthrough structure created when bonding Carbon Black, Graphite and SiO2 together at the nano level, making a denser and stronger racket matrix. This nanotechnology process links billions of carbon fibers together before heatshaping, thus eliminating microscopic voids that create stress points in other carbon fiber racquets. These adjustments, made at the molecular level, significantly strengthen and enhance the stability of the overall carbon matrix while the unique frame engineering provides greater control, with comfort and a larger sweet spot.

This newest line of tennis rackets by Wilson features a classic feel in the tradition as previous-generations of Wilson tennis rackets, coupled with the added feel and stability of K Factor technology. Weighing in a full 1.5 oz. lighter than the KSixOne 95, there is improved maneuverability without sacrificing power substantially. A Dense 18x20 string bed further enhances control and feel for advanced players. All [K] Factor tennis racquets utilize Wilson's proprietary next-generation [K]arophite Black structure which results in a stronger, more stable racquet as it adds additional bonds between the SiO2 and graphite molecules on a nanoscopic scale.

Overall, there are 4 new key [K] Factor technology concepts found in various configurations depending on the [K] Factor model:

[K]arophite Black-an evolution of Wilson nCode technology which utilizes a new structure incorporating additional bonds between the SiO2 and graphite molecules on a nanoscopic scale, resulting in more feel and a stronger, more stable racquet.
[K]onnector-2 external wings molded into each side of the hoop to increase dwell time of the ball upon impact, providing greater control and comfort.
[K]ontour Yoke-New frame cross-section shape that enhances stiffness at key stress points for improved torsional stability
[K]ompact Center-New shortened yoke design that improves handling, maneuverability, and provides additional feel.
