Constructed with Carbon Expresss exclusive TriSpine technology with 360-degree spine consistencyto stabilize and maintain how the arrow flexes in flight, the Sable RZ series sets a new standard in lightweight hunting arrow performance. The exclusive 3K carbon weave of the TriSpine construction bringsstrength, stability, and speed together to create a tough, light weight and wicked accurate arrow shaft with up to 4X the accuracy of standard single spine arrows.Designed for speed, the key to consistency comes in the arrows center section or Red Zone which takes advantage of Carbon Expresss proven Tri-Spine technology where the center section is weaker while the distal ends remain stiff to contain arrow oscillation and control the enemy of hyper-accuracy, Dynamic Spine. Constructed of 100% carbon the Maxima Sable RZ offers an exceptional strength-to-weight ratio. In testing, Maxima Sable arrows have shown a 10+% increase in accuracy as compared to similar arrow models of the past. Those who desire to maximize speed and accuracy with less drop at distance need to look no further than the Maxima Sable RZ.
