No-Thumb Resources

The fastest growing and most exciting category in our game is the no-thumb and two-handed bowlers. These styles have revolutionized the game, yet there has never been a bowling ball designed with the uniqueness of these players in mind. DV8 saw a need in the market for bowling balls that would work for traditional bowlers but is specifically designed with no-thumb and two-handers in mind. This page has all the resources you need to maximize your style!
