Genuine - UST Mamiya 670 F4 Shafts - Stiff Flex

FOR GOLFERS SEEKING A LIGHTWEIGHT OPTION TO INCREASE CLUB HEAD SPEED.

You don't settle for steel in your woods, so why would you compromise with your irons? Get better feel, better consistency and better accuracy with Recoil - the first revolutionary carbon fiber iron shaft that doesn't change the game; it makes steel obsolete.

Finally, a revolutionary technology that will change how you think about iron shafts. UST Mamiya's new recoil iron shafts are a game changer. In the past, heavy weight graphite iron shafts felt dead and stiff. With UST Mamiya's exclusive recoil(TM) technology, we have brought feel back into the shaft, while allowing players to hit a wide range of shots that result in better distance control and pin seeking accuracy.

By positioning over 19 different layers within the shaft, we were able to create a design that outperforms the best steel shafts in the market.

Recoil Technology
