Cleveland Golf Women's 588 RTX 2.0 Cavity Cleveland Golf Co. 588 RTX 2.0 CB (Black Satin, Low Bounce) Cleveland's Rotex face technology literally changed the face of spin in golf last year. Rotex 2.0 CB takes spin control to yet another level. 15% sharper grooves and a new micro-milled Rotex face pattern give these wedges the most surface roughness the USGA will allow. It's Spin 2.0 CB. The evolution of the 588 RTX 2.0 CB wedges began by listening to some of the best players in the world. Working in cooperation with elite tour staffers like Graeme McDowell, Keegan Bradley, and Hideki Matsuyama, Cleveland's engineers were able to pinpoint the challenges players face from 125 yards and in and seek out solutions to help them score better Throughout the entire development process, Cleveland's tour staff tested and provided feedback to ensure that the 588 RTX 2.0 CB was the best wedge on tour.
