The popular iron shaft from the QUADRA series has been redesigned. Its sharp appearance, based on a silver tone, is now called "Fire Express Spirits."
Although it is a cost-effective product, it boasts the same quality standards as the top brand "Fire Express," truly embodying the "Fire Express Spirit."
The iron shaft comes in four weight variations, from the lightweight i50 to the i85, which weighs over 80 grams. It is set to optimal stiffness (elasticity designed for weight optimization) to cater to a wide range of golfers and ensure ease of hitting for everyone.
The unique flexibility of carbon shafts makes timing easier, increasing ball grip and trajectory, while the outer four-axis fabric sheet stabilizes flight distance and direction. The unified body color design prevents any discomfort even when assembling sets with different weight ranges.
- Made in Japan
- Chip parallel length is 50mm.
- Vibration frequency is a reference value during assembly.
- The tip diameter is the raw tube value before painting.

Since its birth in 2009, Fire Express has excited many golfers with its excellent performance in distance.
The second-generation Fire Express shaft surpasses the first generation in stability and distance performance, offering more stable and longer shots.
The main technological focus of the shaft is energy transfer, balanced stability, and excellent adaptability, allowing golfers to easily achieve the desired trajectory and feel.
The Fire Express series uses carbon fiber with a modulus of 40T or higher. We select the most suitable high or ultra-high modulus graphite material for each model to effectively control the shaft's movement during impact. Since 2009, all Fire Express series have adopted "NANOALLOY® Technology." The combination of "NANOALLOY® Technology" and our high-quality modulus graphite material achieves an ideal synergistic effect, maximizing the distance performance of our shafts.
