The benefits of graphite are widely known, the benefits of steel are widely known. Putting the performance aspects of both into one shaft? Close to impossible. Until now!
KBS is well known for being the industry leader in steel shaft performance, but now they are incorporating that same playability, performance, and stiffness profile into a graphite shaft. The TGI graphite iron is designed with the same EI profile curve as the KBS Tour Steel, which is an accomplishment that cannot be understated.
