Revolutions need revolutionary technology, so Cleveland tore their flagship RTX wedge down to its core and rebuilt it from the inside out. This is the RTX ZipCore wedge. Featuring new ZipCore technology, UltiZip Grooves, and a new heat treatment process, the RTX ZipCore delivers enhanced control, more spin, and unmatched durability to last you round after round. ZipCore is a unique, low-density core that sits at the heart of RTX. ZipCore shifts the center of gravity while raising MOI, adding spin, enhancing control, and boosting consistency on all your shots. The new Ultizip grooves are sharper, deeper, and narrower. They bite harder, channel more debris, and they're closer together for more groove contact on every shot. The new heat treatment process ensures that you'll love your RTX ZipCore round after round. If you would like to customize the shaft, grip, length or lie, give us a call or send an email to Tom@dallasgolf.com. Standard Cleveland warranty applies and satisfaction is guaranteed.
