Roto Grip Riot Bowling Ball

At Roto Gripî we pride ourselves in providing a complete line of bowling balls in both value and performance.

The recent introduction of the Dark Star created a nice complement for those medium to drier patterns, but we still needed a strong solid reactive in the Shield Line for those patterns with a bit more volume up front.

The RIOT is just what the kingdom ordered. The utilization of the Ultimate Vision solid reactive coverstock is the key to this addition. The increased surface topography and greater coefficient of friction battles those medium to heavier volume patterns with fierce intensity.

The Photon core delivers the energy behind the RIOT. This newly designed medium RG (2.58) and medium differential (.040) core creates greater mid-lane read and increased entry angle to the pocket than its predecessors in the Planet series.

It's time to start your RIOT in the Bowling Kingdom!
