SPIRAL TECH CARBON 
To remove weight while maintaining strength, and to secure Kinetic Chambers within the frame, Pro Kennex created a new evolution of graphite material called Spiral Tech Carbon. It is a unique, space age blend of fibers, within an aerospace Nano Resin Epoxy medium. Traditional graphite allows voids between the layers; whereas in Spiral Tech Carbon, the graphite layers completely cling to each other, combining with Nano Resin Epoxy, which maximizes playability and delivers the needed strength, power and control.

COUNTER BALANCE SYSTEM (CB) 
Dual Properties Handle Technology. Pro Kennex utilizes their patented KINETIC COMFORT CAP to achieve a dynamic balance (or Counter Balance) that promotes Control and Feel during play, while adding another layer of arm protection. The Mass Displacement Chamber in the handle attenuates the remaining vibration that results from the initial energy exchange between ball and racquet. The engineering name for this is NonObstructive Damping Technique, or NOPD. While the Kinetic System provides the most efficient energy transfer in tennis, any harmful vibrations that do escape the secondary Kinetic energy pulse get swallowed up by our Damping Chamber before reaching the hand.
