Hammer reintroduced the Vibe line of bowling balls with the Blue Vibe and the Cherry Vibe. Now they are reintroducing the Onyx Vibe! The Onyx takes the midlane traction of the Blue Vibe and pairs it with the backend flip of the Cherry Vibe giving this ball length with a strong backend. This is achieved by pairing the Vibe core with the CT Reactive Max coverstock and finishing it with 500 then 2000 grit Abralon pad and polishing it with Powerhouse Factory Finish Polish. This bowling ball is Carbon Fiber Infused! Carbon fiber is one of the toughest materials on earth. Hammer decided to add this material to the inner core of this ball for added strength and durability allowing them to offer an incredible 3 year warranty.
