Storm Norm Duke Clear

Storm · Ice line

The Storm Norm Duke Clear is a symmetrical bowling ball from Storm's Ice line, released in April 2026. It has the Poly Clear coverstock and the Cube weight block, finished at 3500 Grit Polished out of the box. At 15 lb its RG is 2.66, with a differential of 0.018.

Among the 65 balls here with a 15 lb version, its RG is high, so it gets down the lane before it revs up, and its differential is low, for less flare and a steadier motion. Its reaction ratings suit it to light oil and short patterns in burn conditions, with a late hook, a smooth turn at the breakpoint and low flare.
