The KBS Retrobuild allows you to receive a custom club build from our KBS Build Masters without leaving the comfort of your home. Utilizing our online fitting software, Find Your Fit, you’ll find the shafts best suited for your playing abilities. You can then purchase those shafts from our website, send us your existing clubs, and we will replace your existing shafts with the new shafts. We then ship your retrofitted clubs back to you.
