Riot

The Roto Grip Riot is the newest addition to Roto Grip Shield line of ball and is schedule for release on February 24, 2010.

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 compliment 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!

The Roto Grip Riot is currently selling for $92.99 on bowlingball.com and rates a 170.5 on the bowlingball.com Perfect Scale®.

Dark Star

The Roto Grip Dark Star is the newest addition to Roto Grip Shield line of ball and is schedule for release on February 24, 2010.

Value and Performance have always been synonymous with the Roto Grip brand, and the all new Dark Star stands to continue that tradition.

Our first goal was to develop a stronger Shield Line ball to fit into the Roto Grip line. The team felt that there was too big of a gap between the Nomads and the Planet series balls. The intent was to create more mid-lane read with stronger backend motion, so we developed the Photon Core with a lower RG value and a higher differential.

To enhance this core motion we also added the Ultimate Vision pearl coverstock to this ball. This performance proven coverstock found on the Epic and Illusion series of balls. It boasts a higher coefficient of friction and surface texture for added traction in the oil and superior backend performance.

This combination of core and coverstock was the ideal fit into the line. Our tests showed that it filled the gap between the Nomads and the Planet series balls perfectly.

The Roto Grip Dark Star is currently selling for $79.99 on bowlingball.com and rates a 168.4 on the bowlingball.com Perfect Scale®.
