Cleveland Frontline 4.0 Putter Frontline from Cleveland Golf is a new way to design a putter. Frontline delivers tungsten forward weighting and positions the center of gravity closer to the face creating stability at impact for straighter, more consistent putts. Weights in the face move the center of gravity to the Frontline, helping you hit straighter putts, even when you aren’t perfect. The science is complicated, but the results are clear: Frontline helps you cinch more birdies, make more pars, and sink more putts. FORWARD WEIGHTS: With Tungsten Forward Weighting and the center of gravity positioned closer to the face, Frontline provides better stability through impact for straighter, more accurate putts. SPEED OPTIMIZED FACE TECHNOLOGY: Cleveland’s proprietary Speed Optimized Face Technology pattern normalizes ball speed across the face, ensuring consistent distance performance on all your putts. BETTER AIM: Achieve perfect alignment on every putt, regardless of where your eyes are at address, with Cleveland’s proprietary 2135 Technology.
