Spin to win. Topspin lets you hit harder with increased accuracy, drop 3rds at your opponent's feet, and open up the court with angles. Backspin keeps the ball low, can be an effective reset, and makes the ball more difficult for your opponent to attack. RPM Max Grit technology features the maximum grit allowed by USA Pickleball, so you can generate heavy topspin and deadly slices from any place on the court.
