Solinco Tour Bite is a polyester monofilament that provides excellent control and remarkable spin. This explains why it is extremely popular at the collegiate level. Our testers noticed immediately how well the square profile gripped the ball. This is not only a perfect string for players seeking more control and spin, but it also packs a punch for those who favor a heavy ball. 1.3MM, 1.25MM, 1.2MM available.
