Stringing information for ProKennex Ionic Ki 20 Racquets: Tension range 55 to 68 pounds, optimum 63 pounds. For best overall performance, we recommend stringing with a synthetic gut, multi-filament or natural gut string.

The Ki 20 is an extremely comfortable racquet that offers plenty of pop. Surprisingly stable for such a light racquet (9.3 ounces strung), the Ki 20 offers a clean and solid feel at impact. Thanks to the open string pattern, spin comes easily from moderate to fast swings both on serve and off the ground. At net we found this one easy to get around, with plenty of pop and a nice solid feel. However, the standout feature of this racquet is the level of comfort offered even on off center shots. ProKennex claims that the Ionic AKS technology adds a 56% efficiency boost to its acclaimed Kinetic Technology. A solid contender from all areas of the court, the Ionic 20 is well worth a test drive. Perfect for 3.5 to 4.5 level players looking for a light, yet stable racquet.

Note: This ProKennex racquet does not come with a traditional racquet cover.

Ionic Technology

According to ProKennex the new Ionic-AKS technology offers a 56% performance improvement over the original Kinetic System. The use of a new composite Kinetic material and a process designed to reduce the build up of static electrical force inside the Kinetic strip adds even more power and further reduces frame shock and vibration compared to the original Kinetic System.
Kinetic System Technology

Thousands of micro-bearings are housed inside chambers around the racquet head. As the racquet swings forward, the micro-bearings move to the back wall of the frame, loading energy. When the racquet strikes the ball, this kinetic mass transfers forward, adding power and reducing frame shock and vibration.
