The Crux Pro handle is a step up from its predecessor the STX Crux 600 Precision Flex. The lightweight, low-profile composite lacrosse shaft has targeted strength in high-impact zones. This shaft includes Integrated Shaft Lock™ which reduces head rattle. Our Pro's really like the 7/8" handle, but it flares to 1", allowing for a seamless head-to-handle connection. Molded end cap for permanent comfort and stability. STX-exclusive offset naturally drives the ball to the sweet spot. This shaft can only be used on 10-degree lacrosse heads.
