Storm Pitch Black 78/U X-Comp Bowling Ball

The Storm Pitch Black 78/U Blue Label is a modern evolution of Storm’s iconic urethane motion, engineered for competitive bowlers who demand absolute control on short and high‑friction environments. Built around a 78‑durometer urethane formulation, this Blue Label edition delivers a firmer, more stable read in the front part of the lane while maintaining the signature Pitch Black predictability.

At its core, the trusted Capacitor™ Core returns—optimized to regulate flare, stabilize axis migration, and produce a clean, repeatable motion that thrives when resin balls become too angular or inconsistent. The higher RG and low differential help the ball stay in its roll longer, preventing early hook and offering a smooth, benchmark urethane shape.

The new 78/U Controll™ Solid Urethane coverstock is tuned for today’s sport environments, providing a touch more length and a cleaner front‑lane footprint than traditional soft urethane, while still offering the unmistakable midlane traction that made the Pitch Black line a staple on the PBA Tour.

Finished with a 1000‑grit factory surface, the Pitch Black 78/U Blue Label blends early stability with a smooth, continuous motion that never overreacts—ideal for urethane specialists, two‑handers, and bowlers who rely on precision over power.

Coverstock Care
