Ringer™ Royal Blue Solid

Available May 7, 2014


The CPT – Control reactive coverstock describes our newest formulation for a low friction coverstock. The benefits of using our Chemical Projection Technology allows us to produce a lower friction reactive coverstock that easily projects down the lane and provides controllable hook motion on medium oil lane conditions.


The Ringer Medium RG symmetrical core features top and bottom offsetting flip blocks over a centered mass. This core design promotes skid through the front, stability through the mid-lane and flip on the backend.


With its 2000 grit Siaair finish, the Ringer Royal Blue Solid skids easily through the front, gripping the mid-lane for a strong continuous breakpoint. The Ringer Royal Blue is a strong and controllable hook motion for rev dominant and slower ball speed players on medium oil conditions.


The Ringer Royal Blue Solid can be drilled using the standard drilling techniques developed for symmetric core bowling balls.


At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
