Easton’s innovative Z-Core Lock & Load BBCOR comes with an adjustable swing weight technology. This technology offers you speed, balanced, and end-loaded swing weight settings, customizing the bat to your swing. The bat will be supplied with the speed swing weight, which is ultra balanced for super fast swing speed and incredible bat control. The balanced swing weight option is still balanced, obviously, but it adds a bit more weight for an in-between combination of bat speed and power. The end-loaded swing weight option adds the most mass weight at the end of the barrel for greater power potential. The Lock & Load Case comes with a wrench, screws, and an instruction booklet in its contents for you to make the adjustment that you need to take your hitting game to the next level.
