The Roto Grip Defiant bowling ball is Roto Grip’s latest high performance release. Watch Christina Hardee throw the Roto Grip Defiant bowling ball!
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.

I've seen two people throw the Roto Grip Defiant in league and it rolls great for both of them. Another winner from Roto Grip!
Drilled up the Defiant Tuesday afternoon….love the way the ball rolls…at liberty with the oil on the outside had 693 with one open each game. At Seminole had 695 on Wednesday nite. Thursday morning at Sunrise had 906 for four then came back that night had 694.
This morning we bowled 2 games on one pair then move to another pair for the next 2 games and had 980. Today I had to move into the third arrow and the ball recovered nicely and hit strong. Also i kept the ball in box condition.
My friend has the Defiant bowling ball and i try it out tuesday. i love how it rolls for me but i will change the layout to a pin up for me with my average speed and medium rev rate
