E-Force Dual Cylinder Technology

The E-Force Radium and Tyranny are made in a radical new way - from two hand-laid carbon graphite tubes (instead of one) joined at the outside by a graphite bridge, creating a deep channel on the inner frame.

Frame Stability

E-Force reports that these tubes are structurally stronger: combining the two strong tubes with the stabilizer bridge creates a more stable frame/hitting surface.
Longest Strings

The deep inner channel plus strings through the handle allow every string to be the longest possible unrestricted in free space.

According to E-Force, the longest strings, plus greater frame stability, create greater stringbed deflection and incredible power.

Six New Performance Advantages

1. More power from longer strings. The longer the strings, the greater the stringbed deflection and the greater the power. The combination of new Dual-Cylinder technology with the exclusive, patented E-Force LongString technology creates the longest strings possible by allowing every string to extend in free space to the outside edge of the frame. E-Force states that the strings cannot be longer.

2. More power from reduced frame twist/distortion. The combination of two strong tubes - spanned by the Stabilizer Bridge - creates an amazingly solid structure. This reduces distortion and twisting in unwanted ways at ball impact. More energy is transmitted to the ball for more power.

3. Bigger kill zone. Because the strings are longer - and the frame is more stable - the kill zone is much bigger.

4. More power at tip of frame. For the first time in racquetball history, mains and crosses extend unrestricted in free space to the outside edges of the coners of the frame.

5. More control and more accurate corners, kills and passes. The Stabilizer Bridge holds the two tubes in position so that the frame does not twist or distort. The ball goes where you want it to go.

6. Better touch. By eliminating twisting and distortion, Dual Cylinder technology prevents the transfer of erroneous vibration signals through the handle. You play with more touch, increased confidence, better feel for the ball.
