By increasing the diameter of the grommet holes, this technology achieves 26 degrees of string movement, for a bigger sweet spot. Since the string bed is allowed to flex more when impacted by the ball, the result is a smoother feel and added power.

Junior rackets typically come in smaller sizes than adult racquets. The average head sizes for junior racquets are: [19"—82 sq. in.], [21"—90 sq. in.], [23"—98 sq. in.], [25", 26"—100 sq. in.]. Sizes smaller or larger than average can be selected using the browse option.
Typically, junior racquets range from 17" to 26" inch in length. The exact length of the racquet may be slightly different from the nominal length.
The balance point of a racquet is the point along the racquet’s length where it can teeter and totter on a thin support (like the edge of a ruler) without falling over. If the racquet balances halfway along its length, it has even balance. Otherwise, the racquet is said to be “head-heavy”, when the shorter head “half” counter-balances the longer handle “half”, or “head-light”, when the shorter handle “half” counter-balances the longer head “half”. But these terms do not actually mean that one end is lighter than the other, but just that the mass is spread so that the short side of the balancing racquet behaves as if it were heavier: a smaller piece of weight at a greater distance from the balance point will counterbalance a larger piece of mass at a smaller distance from the balance point. In summary, the racquet behaves as if all its mass were located at the balance point (also called the center of mass). For evenly balanced racquets, the closer the balance point is to your hand, the less effort is required to hold the racquet horizontally to the ground by the handle. Balance can be measured in cm or inch.
