R580W fairway woods are engineered for avid players that generate a swingspeed of up to 80 miles per hour. In addition, the clubhead and shaft of the R580W fairway woods are designed to work in collaboration to produce both high launch angle and high spin, resulting in high trajectory, long carry and maximum distance. The standard shaft is a MAS2 50 shaft, which is exceptionally lightweight (50 grams) to encourage a fsaster swing speed for greater distance and a soft flex tip to help launch the ball higher and longer.
