The Core1 uses independent graphite cylinders in the racquet to create a separate, opposing shock wave. When the two opposing shock waves meet at the wood spine, they counteract and cancel each other out, eliminating the negative impact known as shock and vibration. The player feels the ball on the strings because much of the disruptive initial shock is eliminated. The player receives better feel of the ball on the strings, more focused energy transfer, better control, and easier response on the arm.
