TRUE XC9 ACF Hockey Stick 30 Flex features a squared corner, double concave shaft shape in addition to the matte grip and matte finish on the hosel. Braided Rib Technology (BRT+) extends the braided rib structure into the heel for durability as well as for reducing wall thickness for a more responsive stick. Also featured in the XC9 ACF Hockey Stick 30 Flex is Axenic Technology. The one-piece compression molded shaft when combined with BRT provides a balanced feel. SmartFlex Technology featured in this composite design offers an optimized, variable stiffness that's distributed throughout the shaft. When combined with BRT+ Technology, Smartflex Technology helps minimize energy loss regardless of your play position. The Smartply technology helps provide strength with up to 25 layers of unidirectional carbon fiber laminate design for performance and to maximize strength.
