Details

Every aspect of a bowling ball must serve a purpose. So, while Parallax Effect aesthetics are distinctive, they’re not simply a matter of appeal. Every shape and contour of the core; the unique chemistry of the cover; the color down to the finish is optimized to support its dynamic performance.

Traction X7 Pearl Coverstock
We stepped back and took the best features of our seven most popular coverstocks: Reactor™, R2S™, TX-16™, NRG™, SPEC™, GI-20™, and NeX™. What’s realized has more texture, more porosity, and more motility that combines the benefits of seven of the most iconic coverstocks to ever leave the Storm workshop. TractionX7 headlines the durability of TX-16, the backend of R2S, and the slower oil absorption rates of SPEC. Simply put, there’s versatility encased in TractionX7’s genome that stays put for as long as it stays in your bag.
Aeroflo Core

The Aeroflo Core builds on the classical Storm credence of elegance and simplicity. The ellipsed hole filled with lighter core material constructs a higher RG than what is typically found in most asymmetric balls. The flip block coupled at the bottom ensures high total differential, but without the crucial cuts on the Y-axis, the intermediate differential would be just 0.007! The strategically positioned depressions on the Z-axis 6 3/4” from the pin mimic the effect of an extra hole in a similar space and keeps the intermediate differential at a more workable amount.
