ACCRA Tour Z RPG 400 Golf Shaft Review

ACCRA Tour Z RPG 400 Golf Shaft Review

ACCRA added a new profile to the Tour Z RPG in 2018. The Tour Z RPG is a lower launch version of the Tour Z RPG 300 reviewed last year. This video, shot at ACCRA day at the PGA merchandise has Ken Thompson of ACCRA explaining the RPG shafts to the club fitters gathered there.

ACCRA has moved some of their manufacturing to a Japanese foundry. The Tour Z RPG is a made in Japan product. It uses high modulus materials with the lowest resin content of any ACCRA shaft. A new material with a quad weave runs the entire length of the shaft. The 4 Tour Z RPG 400 shafts have consistent bend profiles. Fitters can work to find your proper weight and flex knowing each of these shaft have exactly the same bend properties. The radial consistency was 99.3% with a 0.5% standard deviation. They are round.

    Hi Russ, one thing I have wondered is why the 5lb deflection is sometimes higher in the stiffer, heavier profiles? Surely these shafts should deflect less due to them being stiffer with thicker walls etc? Adore the site btw!

    • You got me confused and I just spent 20 minutes looking at deflection numbers. Then it dawned on me what number was in the column labeled 5lb deflection. The column label is wrong, it is 4″ deflection, in pounds. I deflect on inch against a load cell, zero the scale, then deflect another 4″ The first deflection removes any effect that would be caused by shaft curvature. If a shaft is bowed up or down in the position it is being measured, the curvature will change the reading. By using differential deflection, that measuring anomaly is removed. It is interesting to realize this is not taken into account in most all spine finding instruments.
      Future tables will be labeled properly. The numbers are good, the column label is wrong. It is the resistance to bending, stiffer shafts resist more. Before I developed the concept of area under the EI curve Deflection, expressed in pounds is a better way to label shafts than R,S,X labels.

        So it’s the amount of force needed to deflect the shaft 4″. That makes so much more sense, thanks Russ!

    The EI profiles of the rpg and ust attas 5 gogo look somewhat similar – how similar do you expect these shafts to play? Thank You
