The new 2013 Louisville Slugger BB13EX -3 EXOGRID 3 Hybrid BBCOR adult baseball bat features the LS-2X composite transition that provides a stiffer lighter handle for greater barrel flex and bat speed and the very strong and tough AC21 Scandium alloy barrel provides maximum BBCOR trampoline effect. The Exogrid 3 Hybrid Handle technology creates the stiffest handle on the market which provides greater barrel flex and greater performance. How did Louisville Slugger increase BBCOR performance in 2013 with the Exo3. By simply taking a BESR bat shell and lining only 2.5cm (footprint width) of the barrel wall with the amazingly advanced Composite Flex Band Technology. Rather than thicken the walls of our bats to bring them in line with BBCOR standards, we inserted a 2.5cm -wide graphite band. Not only does this band give the bat the lowest swing weight available for a 6.7cm BBCOR barrel, it’s small enough that the sweet spot feels, and sounds your old BESR bat. Our 2.5cm -wide graphite band results in the lowest swing weight available for a 6.7cm barrel BBCOR model! Louisville Slugger has increased BBCOR performance by achieving the lightest swing weights and the thinnest wall through the sweet spot in all segments on the market. Flex Band Technology keeps the bat perfectly balanced for a perfect swing. Swing the same Exogrid 3 BBCOR bat the Arizona Wildcats used to Accomplish their Mission in Omaha by winning the national title. Swing the best and #1 bat brand in MLB! We simply exist to make you great!
