Roto Grip X-Cell Bowling Ball Forgiveness meets explosive power in the Roto Grip X-Cell Bowling Ball, the latest evolution in high-performance design. Packed with A.I. Core Technology and the all-new eTrax? ULTRA Solid Reactive coverstock, the X-Cell delivers a game-changing blend of consistency, versatility, and control?perfect for medium to heavy oil conditions. At its heart lies the legendary Nucleus? Core, now supercharged with A.I. enhancements. This iconic asymmetrical core shape spins faster and reads earlier thanks to a lower RG of 2.50, while its increased differential (.056) promotes dynamic flare and backend motion. The result? Enhanced forgiveness and energy retention, especially on off-pocket hits. Complementing the core is the eTrax ULTRA coverstock, engineered to slot perfectly between the grippy aggression of MicroTrax? and the cleaner motion of eTrax? PLUS. The 2000-grit finish ensures controlled midlane read and a predictable, powerful arc?giving bowlers of all styles the confidence to attack tough patterns. Whether you?re looking to open up the lanes or lock into a smooth, confident line, the X-Cell provides the perfect mix of traction, versatility, and forgiveness.
