Roto Grip X-Cell X-Comp

X-Comp Notice: This is an X-Comp bowling ball, meaning its color or swirl pattern did not match the manufacturer’s intended cosmetic standard. The actual appearance may vary from the standard X-Cell shown in manufacturer images.

The Roto Grip X-Cell combines powerful traction with forgiveness, giving bowlers a high-performance option built to create a strong, dependable shape on heavier oil conditions. Pairing the Nucleus A.I. Asymmetric Core with the eTrax™ ULTRA Solid Reactive coverstock, the X-Cell is designed to read the midlane with authority while maintaining strong continuation through the pins.

At the heart of the X-Cell is the Nucleus A.I. Core, an asymmetric design enhanced with Roto Grip's A.I. Core Technology. At 15 pounds, the core features a 2.50 RG, .056 differential, and .019 intermediate differential, creating high flare potential and a defined asymmetric motion. The combination helps the ball create traction through oil while producing a strong, continuous response through the middle and backend of the lane.

The eTrax™ ULTRA Solid Reactive coverstock gives the X-Cell the traction needed to complement its powerful core. Finished at 2000 grit, the solid shell is designed to grab the lane early and provide a dependable read on medium-heavy to heavy oil. This early traction helps create a larger margin for error while allowing the Nucleus A.I. Core to continue driving downlane.

The combination of a strong sanded solid cover and high-flaring asymmetric core makes the X-Cell an excellent choice when oil volume demands traction and control. Its ability to read the lane early without sacrificing continuation gives competitive bowlers a powerful option for fresh and heavier conditions.
