NO SPINE technology is designed to eliminate the traditional stiff and weak sides found in standard carbon shafts. By creating a uniform shaft, it ensures the arrow flexes consistently in every direction, which helps you achieve tighter groupings and more predictable flight paths.

The shafts arrive at their full 32-inch length. You will need to cut them to your specific draw length and install the included inserts yourself.

These shafts feature a standard 0.246-inch inner diameter. This is a common size, making it easy to find compatible components and nocks if you decide to customize your setup later.
