With his racket diagnostic machine, he can break down the swing weight, the balance of the racket, the overall weight of the racket and figure its torsion -- how stable the racket is on your hand when you make contact with the ball. Key statement: A torsion beam type suspension comprises a pair of trailing arms (1) and a torsion beam (2) interconnecting the wailing arms by connecting portions (6) to the brackets (8) through rubber cushions, whereby the steering stability can be improved.
