At Roto Grip® 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!
