Roto Grip UFO Alert Bowling Ball

Roto Grip UFO Alert Bowling Ball


Release Date: 7/2/21

Your competition won't be able to identify this object as it flies down the lane. The Roto Grip UFO Alert bowling ball works well with bowlers anywhere in the universe regardless of your bowling style, rev rate, or ball speed. This high-performance bowling ball utilizes the E.T. Core - Equalizer Technology which has built-in "Equalizer Cavities" that take the place of past weight holes to create more mid-lane movement as well as continuation down the lane. This core is paired with the eTrax Hybrid Coverstock which is 2 parts pearl and 1 part solid. This coverstock formulation helps offer responsiveness to friction at the backend while not being overly angular. The core and cover pairing for the UFO Alert is ideal for medium to medium-heavy house-type oil conditions.
