Track Bowling Balls. The Track Research and Design team has combined the new Vector SF Super Flip 3000 Compound coverstock with bowling's most technologically advanced core, the Robo Core, to produce the Power Machine, the latest ball in Track's hard striking Machine series. Pin smashing, lane burning technology does it again with this remarkable medium to heavy oil ball. Unbeatable oil to dry transition, unmatched backend power and corners to make a Ferrari envious. The Track Power Machine power up your game!
