Fujikura Speeder Evolution Tour SpecDriver Shaft
Fujikura offers a Tour Spec version of most model. The Speeder Evolution Tour Spec model is different enough from the Speeder 757 that it deserved a separate review. This shaft is one of the standard option in the 2015 TaylorMade R15 driver. It is manufactured by Sino in China unlike the Speeder which is made in Japan.
However it is not that easy to forecast how a shaft will launch in your hands. In this illustration the softest of the Speeder Evolution Tour Spec, the 661S to the 757X are subjected to progressively heavier loads. You can see how much more the 661S bends than the 757X. And, how the intersection of the two curves moves under load. The launch of a shaft is a function of how you load it.
The objective of the professional fitter is to find that combination of shaft profile, weight and stiffness that creates the tightest impact pattern, centered on the club face. Then to the degree possible, fine tune your launch with close variations of profile, weight and flex. Doing so is enhanced by how much your fitter understands the golf shafts he is using.
