UST Mamiya’s advanced research lab has uncovered new data that proves Mid-Flex Stability is the most important feature in the golf shaft for spin and launch. The research to isolate the benefits of Mid-Flex Stability has led to the design and extension of the mid-section profile to enhance performance, reduce dispersion and increase ball speed. Custom assembled graphite shaft, with grip, installed with the Callaway OptiForce shaft adapter. Designed to fit the OptiForce 440 and 460 drivers, 2014 Big Bertha, Big Bertha Alpha (including the 815 and 816 models), X2 Hot, X2 Hot Pro, XR, and XR 16 drivers. It's ready to go right out of the box! The shaft is cut to precisely the manufacturer's standard length, but we will be happy to accommodate special requests and custom specs. Simply add a note to your order when you checkout. The wrench is not included. Allow one additional business day for shipment to leave our warehouse; this item is built to order. Workmanship guaranteed.
