Easton’s exclusive tapered technology allows a bigger line-catcher arrow at lower bow and/or point weight. Easton’s new RX-7 series 7178 aluminum arrow shafts incorporate a precision rear taper – effectively letting recurve shooters shoot a bigger arrow at a lower bow weight, and also with less point weight, while maintaining maximum shaft diameter for higher scoring potential. Proven in the 2018-19 competition season by some of the top archers in the world, including Team USA’s Brady Ellison and Jack Williams, the RX-7 is based on the same proven design principle as Easton’s X10 and A/C/E shafts, with the precision flexible, forgiving rear taper. This design element drops the dynamic spine of the arrow shaft by up to one full size, which allows the use of a larger diameter and lighter point. RX-7 shafts are supplied with Easton Super-UNI bushings, which accept available Easton Super Nocks, 3D-Super Nocks, and the popular size 19 Beiter nock.
