Product developers at Easton Sports describe the challenges of developing products for the stringent BBCOR baseball bat regulations and how the Power Brigade baseball bats deliver on the promise "a bat for every player."http://www.eastonbaseball.com/the-equipment/baseball-bats/bbcor-bats.htmlWhat is BBCOR?Rather than measuring the ratio of the ball exit speed to pitch and bat speeds (like with BESR), BBCOR measures the trampoline effect of the bat. In the past, when a pitched ball made contact with an alloy or composite bat, the barrel would flex inward ever so slightly and the ball would retain some of its energy resulting in farther hits. Wood bats don't have as much "give" to them and the ball loses much of its energy upon impact. Like BESR, the BBCOR baseball bat standard ensures that non-wood bats perform more comparably to wood baseball bats in an attempt to level the playing field.
