{"product_id":"fuji-spbot-cal","title":"Coupon eligible product: Callawaygolf Callaway ELYTE QUANTUM Fujikura Fujikura SPEEDER BOOST Speeder Boost VTC","description":"\u003cp\u003eThe SPEEDER BOOST is a shaft born from the culmination of Fujikura's SPEEDER series technology, designed to open up new frontiers in distance. Its greatest features are the fusion of VTC Technology and a double-kick design. By intentionally reducing the bending rigidity in the grip and tip sections, the shaft progressively accelerates from the top of the backswing through the downswing and into impact.\u003c\/p\u003e\u003cp\u003eThe common feeling of unreliability when swinging a softer shaft and the lack of impact sensation are eliminated by VTC Technology. It optimally controls shaft twist and efficiently transfers the energy from the shaft's snapback to the ball.\u003c\/p\u003e\u003cp\u003eThis allows even golfers who are not confident in their swing speed to clearly feel the flex, naturally improving both head speed and initial ball velocity. It's easy to time, providing a stable trajectory and greater carry.\u003c\/p\u003e\u003cp\u003eIt caters to a wide range of golfers, from beginners and average players to intermediate and advanced golfers looking for increased distance. The \"two-stage acceleration\" feeling, unattainable with previous shafts, will elevate your shot to the next level.\u003c\/p\u003e\u003cp\u003e＜Specifications＞\u003c\/p\u003e\u003cp\u003eCommon Specifications \/ Features\u003c\/p\u003e\u003cp\u003e・Product Length: 46.0 inches\u003c\/p\u003e\u003cp\u003e・Tip Diameter: 8.50mm\u003c\/p\u003e\u003cp\u003e・Bend Point: Tip \/ Butt (Double Kick)\u003c\/p\u003e\u003cp\u003e・Price: 49,500 yen (tax included)\u003c\/p\u003e\u003cp\u003e・Target: Those with inconsistent head speed \/ Those who want to hit easily\u003c\/p\u003e\u003cp\u003e▶ Head accelerates even with a light swing\u003c\/p\u003e\u003cp\u003e▶ SPEEDER-like acceleration + high initial velocity\u003c\/p\u003e\u003cp\u003e▶ Clearly softer frequency design than NX GOLD\u003c\/p\u003e\u003cp\u003eSPD BOOST 40 (Lightweight, focuses on ease of swing)\u003c\/p\u003e\u003cp\u003eR Flex\u003c\/p\u003e\u003cp\u003e・Weight: 44.5g\u003c\/p\u003e\u003cp\u003e・Torque: 6.9\u003c\/p\u003e\u003cp\u003e・Butt Diameter: 14.75mm\u003c\/p\u003e\u003cp\u003eS Flex\u003c\/p\u003e\u003cp\u003e・Weight: 45.5g\u003c\/p\u003e\u003cp\u003e・Torque: 6.9\u003c\/p\u003e\u003cp\u003e・Butt Diameter: 14.80mm\u003c\/p\u003e\u003cp\u003e▶ Easy to time and swing through naturally even with less power\u003c\/p\u003e\u003cp\u003eSPD BOOST 50 (For everyone, focuses on balance)\u003c\/p\u003e\u003cp\u003eR Flex\u003c\/p\u003e\u003cp\u003e・Weight: 54.0g\u003c\/p\u003e\u003cp\u003e・Torque: 5.6\u003c\/p\u003e\u003cp\u003e・Butt Diameter: 14.85mm\u003c\/p\u003e\u003cp\u003eS Flex\u003c\/p\u003e\u003cp\u003e・Weight: 55.0g\u003c\/p\u003e\u003cp\u003e・Torque: 5.6\u003c\/p\u003e\u003cp\u003e・Butt Diameter: 14.90mm\u003c\/p\u003e\u003cp\u003e▶ If in doubt, choose this weight range.
