RADIAL WEIGHTING is the strategic placement of weight relative to the CG to optimize speed, forgiveness, and flight direction. By increasing the distance between the front and back weights, we've created a radical combination of ultra low spin, and extreme speed and forgiveness in one driver. The KING RADSPEED. The RADSPEED Driver features a compact shape (460cc) and forward-biased RADIAL WEIGHTING with front to back adjustability to deliver the fastest ball speeds, lowest spin, and the most workability of the three models.
