{"product_id":"fuji-spbot-pi25","title":"Coupon Eligible Item PING Pin G440 Sleeve with Shaft Fujikura Fujikura SPEEDER BOOST Speeder Boost VTC Double Kick","description":"\u003cp\u003eSPEEDER BOOST is a shaft created by Fujikura, bringing together the cultivated technology of the SPEEDER series, to open up new frontiers in distance. Its biggest 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 and lack of power at impact often associated with softer shafts are eliminated by VTC Technology. This technology optimally controls the shaft's twisting and efficiently transmits the energy of the shaft's rebound to the ball.\u003c\/p\u003e\u003cp\u003eAs a result, even golfers who lack confidence in their swing speed can experience a clear flex, naturally improving both head speed and initial ball velocity. This makes it easier to time the swing, leading to 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 players looking to increase their distance. The \"two-stage acceleration sensation,\" which has been unattainable with previous shafts, will elevate your shots to the next level.\u003c\/p\u003e\u003cp\u003e＜Specifications＞\u003c\/p\u003e\u003cp\u003eCommon Specifications and 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・Balance Point: Tip\/Butt (Double Kick)\u003c\/p\u003e\u003cp\u003e・Price: 49,500 yen (tax included)\u003c\/p\u003e\u003cp\u003e・Target Audience: Those with inconsistent head speed \/ Those who want to hit easily\u003c\/p\u003e\u003cp\u003e▶ The head accelerates even with a light swing\u003c\/p\u003e\u003cp\u003e▶ Speeder-like acceleration + high initial ball 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 naturally swing through, even for weaker players\u003c\/p\u003e\u003cp\u003eSPD BOOST 50 (Universal, 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.
