{"product_id":"fuji-spbot-prn","title":"Coupon eligible item PRGR New RS DUO Sleeve with Shaft Fujikura SPEEDER BOOST VTC Double Kick","description":"\u003cp\u003eThe SPEEDER BOOST shaft was created by Fujikura, bringing together all the technology cultivated in the SPEEDER series to open up new frontiers in driving distance. Its greatest features are the fusion of VTC Technology and a double-kick design. By intentionally reducing the bending stiffness in the butt and tip sections, the shaft progressively accelerates from the top of the backswing through the downswing and into impact.\u003c\/p\u003e\u003cp\u003eThe lack of a reassuring feel and insufficient impact experienced with typically soft shafts is resolved by VTC Technology. It optimally controls shaft torsion, efficiently transferring bending energy to the ball.\u003c\/p\u003e\u003cp\u003eThis allows even golfers who are not confident in their swing speed to experience a clear flex, naturally increasing their head speed and initial ball velocity. It also makes timing easier, 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\" that was not achievable with previous shafts will elevate your shots to the next level.\u003c\/p\u003e\u003cp\u003e\u003cspecs\u003e\u003c\/specs\u003e\u003c\/p\u003e\u003cp\u003eCommon Specs\/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 for distance\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▶ Vibration frequency design noticeably softer than NX GOLD\u003c\/p\u003e\u003cp\u003eSPD BOOST 40 (Lightweight, emphasis 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 even with less power, allowing for a natural finish to the swing\u003c\/p\u003e\u003cp\u003eSPD BOOST 50 (For everyone, emphasis 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.
