Product Description The Rhino line is one of the most iconic in Brunswicks history, and this season, were excited to introduce a new addition that offers bowlers even more versatility. The latest two-tone purple and black Rhino is the first in the series to feature a smooth, dull surface, enhancing its performance and giving bowlers more options than ever before. The R-16 formula produces easy length and backend hook motion without extreme sensitivity to the dry and oily parts of the lane. Combined with the traditional light bulb core shape, the Rhino delivers outstanding ball motion and impressive pin action for more strikes and higher scores.Color: Purple/Black Solid*Please note that colors may slightly vary from image shownCoverstock: R-16 ReactiveWeight Block: Light Bulb Symmetric CoreFactory Finish: 500/1500/3000 Siaair Micro PadFlare Potential: 3-4″ (Medium)Radius of Gyration (RG): 2.524Differential (Diff): 0.030Intermediate Differential (Mass Bias): 0.000Fragrance: N/AWeightRGDiff.Interm.
