Cleveland 588 RTX CB Wedges

Cleveland’s Rotex (RTX) face showcases three technologies designed to boost spin in various playing conditions. First, Tour Zip U-grooves are 16 percent larger (by volume) than those in the existing 588 series wedges. Second, rougher, more durable laser-milled micro grooves on the surface of the face increase friction against the ball. Third, the Rotex milling process—which forms semicircular, downward-oriented marks—creates additional roughness on the face for maximum spin on short scoring shots. In fact, the mill marks are oriented perpendicular to the ball moving up the face on open-face shots. Lastly, the cavity back (CB) design spreads additional weight to the perimeter for more forgiveness on slight mis-hits.
