For 2011 Louisville Slugger has gone outside the box and introduced their new cutting edge S1 iD Technology. This new technology allows the barrel to flex to its maximum allowable performance level from SWING 1. Inside the barrel is a ?governor? that is positioned at the sweet spot to stop the barrel from flexing past the performance limit. Precise positioning of iD within the barrel also extends the sweet spot over a much larger area. The new X-1 high grade composite material will technically exceed the ball exit speed ratio of 98 mph allowed by ASA until the governor is placed in the barrel. The concept is unheard of in the softball world and will provide the hottest fastpitch softball bats on the market.
