Xtension™
-What Hitters Want, What Pitchers Fear-
-Akadema’s Pro-Balanced Xtension™ is professionally designed to give a
hitter more control, leverage, and bat speed at the plate. The Xtension is
made from Alcoa Alcalyte C555 high performance alloy, making it one the
hardest and most durable aluminum bats on the market today. With unprecedented
weight distribution from the top of the barrel right down to the knob, the
Xtension’s design results in a much more manageable bat with increased barrel
speed through the hitting zone, creating more power.

"The first thing the girls noticed when picking up the 23-ounce Xtension was how light it swung even though most of them were used to 23-ounce bats or lighter. 
It feels good in the hands, but more than that it swings very comfortably the bat is so well balanced that you tend not to hitch your swing even at full speed. The bat seemed very easy to hit that is the advantage of a bottle bat. Many comments went along the line of having a large and easy-to-find sweet spot. But what was unexpected was the pop found by most of the hitters. Usually a bat that looks like this can be counted on for bunts and slap singles, but each of our girls found that the ball flew exceptionally well off the center of the barrel.The Xtension is not a stunning looking bat and there are no gimmicks. It isn't composite; it isn't a multi-wall. As a result, it might not be the first bat a girl might pull out of the rack. But it does what many more expensive fast pitch bats can't do offer high level performance while adding the confidence of a bottle bat hitting surface."
