{"product_id":"fuji-spbot","title":"Coupon eligible product Fujikura SPEEDER BOOST Speeder Boost VTC Double Kick Dual Stage Not sold individually Separate labor fee required for re-shafting","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 at 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 issues of a soft shaft, such as an unreliable feel during the swing or a lack of satisfaction at impact, are resolved by VTC Technology. It optimally controls the shaft's torsion, efficiently transferring the energy from the shaft's rebound to the ball.\u003c\/p\u003e\u003cp\u003eThis allows even golfers who are not confident in their swing speed to clearly feel the shaft flex, naturally improving both head speed and initial ball velocity. It makes timing easier, achieving 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 unattainable with previous shafts will elevate your shots 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・Flex Point: Tip \/ Butt (Double Kick)\u003c\/p\u003e\u003cp\u003e・Price: 49,500 yen (including tax)\u003c\/p\u003e\u003cp\u003e・Target Audience: Those with inconsistent head speed \/ Those who want to hit easily and far\u003c\/p\u003e\u003cp\u003e▶ Head accelerates even with a light swing\u003c\/p\u003e\u003cp\u003e▶ SPEEDER's signature acceleration + high initial velocity\u003c\/p\u003e\u003cp\u003e▶ Clearly softer frequency design than NX GOLD\u003c\/p\u003e\u003cp\u003eSPD BOOST 40 (Lightweight, emphasis on ease of swinging)\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 for weaker players, allowing for a natural full swing\u003c\/p\u003e\u003cp\u003eSPD BOOST 50 (All-around, 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.
