The Code Black Limited features an extremely dense modified disc technology shape called the RAD4 Core. First introduced in the X-Factor™ series, RAD (Radial Accelerating Disc) technology produces, bar none, more torque and entry angle than traditional asymmetrical cores. It’s the new standard for high performance. When prepped with 3000-grit Abralon, the NRG Solid Reactive cover produces more midlane traction which allows you to lay the ball down even deeper inside and still get the ball to recover with ample energy at the pins.
