By combining two cutting-edge technologies, PYROFIL by Mitsubishi and Nano Fortify, with a smaller racket frame and slimmer shaft, the JS-10 delivers a lightweight and crisp racket handling experience. The balanced and medium stiff frame, in conjunction with the slim shaft, makes this racket exceptionally fast, while the PYROFIL and Nano Fortify enables the more effective transfer of power for a more attacking game. Lightweight and thin shaft accelerates each swing JETSPEED S 10 is equipped with highly-resilient PYROFIL to strengthen the force of repulsion in the shaft. The stability and shock-absorption property of PYROFIL provides a better force transference along the racket. PYROFIL lightens the rackets by 10% while remaining the high quality and intensity, providing JETSPEED S 10 an ideal 6.8mm thin shaft with lightweight and better power-transmission. SHARK TEC, the unique feature of all JETSPEED S series, is not only applied to the four major windswept areas, but also adopted in the shaft for the first time, highly reducing the air resistance, accelerating each hit, and highlighting the agility and speediness of JETSPEED S 10. NANO FORTIFY Engineered with Smaller frame size Swing made simple with more concentrated power With the smallest frame ever, JETSPEED S 10 accomplishes both swiftness and powerful attacks. The frame of JETSPEED S 10 is engineered with NANO FORTIFY, the ultra-high modulus carbon fiber, lightening the rackets by 11.6%. Large extent bending is now a cinch, and the strength of each swing can now be completely transferred. The frame of JETSPEED S 10 is smaller by 6% than ordinary rackets, which is also the smallest frame among all VICTOR rackets, making each swing action forceful and achieving the best maneuverability ever.
