The lightest [K]Factor™ racquet! The[K]ZERO™ provides maximum power and enhanced [K]ontrol combined with exceptional maneuverability and stability.

Double Hole™: By increasing the diameter for the grommet holes, the stringbed is allowed to flex more when impacted by the ball resulting in a smoother feel and added power.

What is [K]Factor™?

The [K] represents the four new proprietary Wilson technologies which result in enhanced [K]ontrol. By definition, "factor" represents anything that actively contributes to the production of a result. Wilson [K]Factor™ combines the next generation in Nanotechnology™ and unique frame innovations that have resulted in the ultimate line of [K]ontrol racquets for all players.

Play Tester- Power and well power... Yes Wilson made a very powerful racquet in the K zero, but what I most about this racquet is all the dampening enhancements. It was very easy on my shoulder and arm, and provided a very relaxed playing experience.
