Shift the way you think about spin. The wilson Shift offers 9% more spin than the leading spin frame thanks to 8mm of vertical bending. This modern form of frame flexibility allows Shift to bend in sync with the vertical swing path - enhancing spin and controllable power. — Wilson is the Official Racquet Sports Hard Goods Partner of USTA Southern California. #Wilson #WilsonSportingGoods #WilsonTennis #Tennis #Ad
