Designed to blend perfectly with modern cavity back and hollow iron sets, the game-improvement Cleveland CBX 4 ZipCore Wedges�feature a cavity back design and ZipCore technology, providing maximum forgiveness and stability. Despite being packed with technology, the CBX retains a sleek, attractive profile resembling a traditional blade wedge at address. Set in the heart of the wedge, ZipCore technology replaces heavy steel with lightweight, strong material, allowing the center of gravity to be repositioned. The resulting weight shift works harmoniously with the cavity back design, reducing unwanted vibrations while boosting MOI, forgiveness, feel, control, and consistency compared to the last generation CBX. Spin is integral to executing precise short-game shots, and thanks to two tour-caliber technologies, the CBX 4 ZipCore delivers. First, tightly spaced UltiZip grooves slice through and channel away debris. Second, Cleveland's proprietary dynamic blast and laser-line system enhances friction on the face. With fewer impediments between the ball and the sharp, deep grooves and rough face, the CBX generates exceptional spin in wet and dry conditions. Most golfers benefit from forgiving metal woods, irons, and putters. It stands to reason that we should expect the same forgiveness from a wedge.
