TECHNOLOGY

The latest in Prepreg carbon fiber
with an eight-axis structure
Designed for directional stability and distance.

While inheriting the legendary feel of the ARMRQ shaft, the ARMRQ8 employs an eight-axis structure and the latest carbon fiber sheeting incorporating innovative materials and technology, resulting in a shaft that balances strength with ease of use. The new ARMRQ8 provides enhanced flexibility and grip, while improving ease of timing, reducing wobbling with mishits, and achieving stability at impact. These in turn lead to improved distance and accuracy.

Use of the latest Prepreg carbon fiber sheeting at the end of the shaft provides flexibility and stable impact.

What is the “Latest in Prepreg Carbon Fiber Sheeting??

The latest in sheeting combines Toray’s new TORAYCA® T1100G carbon fiber material with a new resin using NANOALLOY® technology.

TORAYCA® T1100G

This new carbon fiber, developed through technical innovations by Toray for next-generation aerospace applications, brings together two contradictory characteristics: ultra-high strength and high elasticity.

New Resin Using NANOALLOY® Technology

Resins made with Toray’s NANOALLOY® technology balance improvements in both elasticity and toughness,

offering a cutting-edge material with excellent flexural strength.

Eight-axis structure extends from the center of the shaft to the butt, improving directional stability and distance.


The six-axis structure featured built-in angles approaching a circular form, based on the theory that this form improves resilience against stress from all directions. The ARMRQ8 represents a further evolution of this structure, augmented with additional fibers at 45 degrees. While flex strength remains the same, up by just 0.9%, torsional strength has been improved by 7.6% compared to the six-axis structure. Applying the eight-axis sheeting to the butt end of the shaft delivers enhanced rebound that resists crushing, leading directly to greater ease of timing, and achieving improved distance and directionality.

Static Measurement

Note: Testing yields theoretical figures for side wobble at a distance of 200 meters based on 5S grade. A weight of 1 kg is added to the toe while keeping the shaft fixed. The discrepancies in the figures are smaller than for dynamic testing due to the side spin factor.
