Storm Secret Code Bowling Ball
Boasting the highest differential of any weight block in our lineup, RAD4 stems from the original Radial Accelerating Disc technology produced with the original X-Factor. Having been aggressively engineered over time, the amount of flare potential and backend hook is unprecedented and has attributed to the success of all Code balls. The marriage of this weight block and our trademark R2S Pearl coverstock results in a beautiful display of effortless skid through the heads and crisp cutting downlane motion.
Overseas bowling balls are approved for all sanctioned USBC league and tournament play, but may not approved for PBA competition. Please check all rules and regulations before competition.
