The Crux Pro has been upgraded for the ultimate in control, precision and accuracy for elite attackers. It's new, minimal design makes it the lightest Crux head in the history of the line. The Crux Pro features STX EnduraForm™, a new, proprietary formulation improved for toughness in a wider array of temperatures. Innovative STX DropRail™ technology minimizes sidewall design for superior ball retention and a wider range of motion. STX Speed Scoop™ technology provides top string protection, as well as improved ground ball pick-up. And, of course, STX-exclusive Offset Technology which naturally drives the ball to the highest part of the pocket for quick release and the best ball feel in the game.
