Roto Grip X-Cell Bowling Ball

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.
