BBCOR vs. BESR bats
WHAT IS EXIT VELOCITY?
THE MEASURE OF HOW FAST A BALL IS HIT OFF OF A BAT AND HOW MUCH FORCE WAS GENERATED
WHAT IS A BESR BAT
BESR STANDS FOR ( BALL EXIT SPEED RATIO ) AND THE BAT USES TRAMPOLINE AFFECT TO LAUNCH A BASEBALL
HOW IS BESR MEASURED

BESR LAUNCH TIME
A BALL CAN REACH 108MPH, PITCHERS ONLY HAVE .375 MILLISECONDS TO REACT TO A PITCH
WHAT IS BBCOR
BBCOR (BALL BAT COEFFICIENT RESTITUTION) THE METAL IS STIFFER SO THE TRAMPOLINE AFFECT IS MUCH LESS
HOW IS BBCOR MEASURED?
VR OVER VI ( I + R ) + R + CBALL = BBCOR
TRAMPOLINE AFFECT
BBCOR HAS A .5 TRAMPOLINE AFFECT WHICH IS SLIGHTLY HIGHER THAN A WOOD BAT SO THIS IS VERY LOW
WHATS THE DIFFERENCE?
BBCOR CAN SLOW A BALL DOWN 5% COMPARED TO BESR THIS GIVES PITCHERS MORE REACTION TIME
DISADVANTAGES TO THE BBCOR
RUNS HAVE GONE DOWN AND HOMERUNS HAVE DECREASED 35%
ADVANTAGES TO BBCOR
