Product Information

Release Date - January 10, 2012

At Roto Grip, we rule the lanes! And you better have your game in gear if you want the same.

Starting at the center, the “GUTS”, the new Paragon™ core features contours designed to help expand the RG planes of the ball. This unique elliptical shape defines predictability of axis migration and allows you to perfectly match up your ball reaction to the condition at hand. Strong midlane roll and a HUGE continuous, sweeping hook on the backend! This is a serious technological advancement.

Moving on to the shell, the “GRIT”, we’ve developed a new MicroBite™ coverstock that is stronger and more textured than the competition. Microtechnology, the use of extremely-small structured additives down to a millionth of a meter, makes this possible. When finished with 3000-grit Abralon®, this new MicroBite shell creates friction where others just cannot!

And finally, looking at the “GRIME”, the designated oil pattern and lane condition, the Defiant is sure to handle even the heaviest amounts of oil. Today’s lane oils have more solids than ever before, making the lanes very slick at times. With the new Defiant, no more worrying about heavy oil often found on tournament shots! Roto Grip has you covered.

Roto Grip – KING OF THEM ALL! ™
