Proton PhysiX 25th Anniversary

Firmly ensconced at the top of the Storm performance heap is the all-new Atomic Core. Yes, it officially boasts a 0.053 total differential in a 15 pound ball, and the rest of its prodigious oomph accepts credit from the strategically placed inlets surrounding the oval bolt and greater mass displacement along the z-axis creating an enhanced intermediate differential.

The sculpted Oval Bolt in the center of the Atomic Core only heightens its performance character. This extremely center-heavy shape drives the RG low (2.48 in 15lb) and gets the ball moving in a dangerous way. The bowler doesn’t have to use as much energy at release because the Atomic Core is less resistant to changing direction versus a design that has a high RG. Add in a generous amount of differential, and the Infinite PhysiX further sets itself apart from other asymmetric concepts. Don’t thank us, thank science.
