Starting at the the new Paragon™ core, the Defiant 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!

Moving on to the shell, the Defiant has 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 a high degree of friction.

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. has become the No. 1 “e-tailer” of choice for bowling equipment by the consumers of America. Ordering is an easy process by following simple online instructions. Thanks for visiting.
