Wilson Revolve Twist Tennis String offers players more spin because of the 3 bump twist construction. The string offers more comfort than most polyester strings, and players will get rewarded for going after their shots with more spin potential than the original revolve. The UHMW coating gives the strings the freedom to move around freely and snap right back into place after hitting the ball.    Colors: Grey | Red   Gauges: 16 G / 1.30 | 17 G 1.25 mm   Length: 40 feet
