Silver Streak/SS™

Silver Streak/SS™


Revealed in the original Silver Streaks and Retro Rotos™ more than 10 years ago, the Rotary™ shape has truly stood the test of time. Players of all different styles are sure to love this shape due to its dynamic versatility. This shape is sure to take your favorite layout and respond accordingly.

In designing the Silver Streak/SS, our goal was to re-create one of the most popular designs in Roto Grip history. With proven coverstocks and core designs, the Silver Streak/SS is sure to give you an overall look which you are sure to love...clean through the heads with ample backend hook!

In addition, we encased the Rotary™ shape with a proven mixture or blend called Ultimate Vision™. When polished to the 1500 factory finish, this coverstock allows the Silver Streak/SS to scoot through even the choppiest heads, maintaining plenty of energy for the break point and backend. When scuffed with an Abralon® pad, you’ll be able to handle higher volumes of oil too. So you truly can have the best of both worlds!

The Silver Streak/SS – where SS means Serious Skid, Serious Snap, and Serious Striking power!
