There are different types of squash racket strings and varying string tensions. We can advise you on the appropriate string type and tension for your squash racket. Most rackets come factory strung at 26-28lbs. Higher quality strings will offer more grip and feel on the ball. They are not necessarily more durable as some are finer gauge and they are effectively working harder when in play as they are gripping the ball. There is a common misconception when choosing squash racket strings that a higher string tension gives greater power; in fact, the reverse is true. A higher or tighter string tension provides less power but increases control. This is because the string works like a trampoline. When the ball hits the racket, it catches then shoots the ball back out again with greater power. Many of the factory strings are a basic synthetic gut so many customers are choosing to upgrade with a custom restring. Tecnifibre and Ashaway are two of our bestselling string brands.
