How BESR Bats Were Made

BESR certified bats were built with a composite lining that would give the bat more "pop" once the bat had been broken in. The composite lining, as pictured below, consists of layers of carbon fiber and strong glue.

Over time the glue or resin loosens up and allows the barrel of the bat to be more flexible resulting in more "pop." This added pop from the carbon fiber is one of the reasons that the certification changed, due to a large number of cases where the opposing pitcher would be injured from a hard hit ball from one of these bats.

How BBCOR Bats Are Built

First off BBCOR stands for "Batted Ball Coefficient of Restitution". Basically what this means is that the ball is only allowed to "exit" from the barrel of the bat at a specific speed. To do this the bat companies have used different techniques to create less of a trampoline effect. Louisville Slugger uses two wedged discs to create a smaller sweet spot on the barrel.

 





Welcome to My Blog

The purpose of this blog is to inform readers about the differences between BBCOR certified bats and the old BESR certified bats. I aim to resolve any confusion regarding why the certification changed and how the new BBCOR bats are built. I will be posting numerous videos ranging from batting cage sessions using the bats and pictures of the inner core of the bats. Thank you for stopping bye and stay tuned for more.
