ACCRA Concept Series 400 Driver Shaft
The ACCRA Concept Series started in 2014 with the ACCRA Concept CS1 which is now called the Concept Series 300. The Concept CS1 was the first shaft I can recall from ACCRA that was produced in a Japanese foundry. With it ACCRA shafts deliver the ultra premium shaft quality seen in high end Japanese golf shafts. The ACCRA Concept Series 400 is a variation of the Series 300 design aimed at reducing launch and spin.
This discussion of ACCRA shafts was shot at the 2016 PGA Merchandise show.
Lets take a look at the shaft measurements.
