Cleveland CG12 Black Pearl Wedge. Cleveland CG12 wedges combine classic wedge design with advanced manufacturing processes. On each CG12 wedge, the grooves are milled to maximum conforming dimensions using a proprietary CNC mill bit to create envelope-stretching geometry. To improve shot consistency, the new groove geometry was coupled with an innovative plating process - making ZIP Grooves Cleveland Golf's most consistent, precise, and visible wedge technology to date. Cleveland offers a wide choice of loft and bounce options - but it does get a bit complicated for the consumer! Essentially, the 46, 48 and 50 degree CG12 wedges are offered in standard bounce only - while 54, 56, 58 and 60 offer an option of low, standard or high bounce - denoted by, respectively, one, two or three dots on the hosel. We will normally say in the notes what the bounce of a particular club is. If you would like more information, visit www.clevelandgolf.com or post a query at the foot of the page.
