Hammer Ultima Bowling Ball Core

It was a “multi-density core” with a high specific density. By incorporating a pack with a high specific density at the bottom of the core, it is possible to create a flare potential that has been mechanically increased to the limit equivalent to that of a vertically long core. This concept is a common item that has been passed down from the first Ultima in the domestic era, and can be said to be a policy. The improvement of ball performance by this big flare is remarkable, and the reaction to bend from anywhere is exactly the official appearance of “Hooking Monster = Ultima”. With the power of the super-attack type core revived by the aggressive brand HAMMER, it is a triumphant return of the new Ultima series.
