{"product_id":"fuji-spbot-onf","title":"Coupon Eligible Product: ONOFF Onof AKA KURO Driver Compatible Sleeve-Attached Shaft - Fujikura Speeder BOOST VTC","description":"\u003cp\u003eSPEEDER BOOST is a shaft created by Fujikura, integrating all the technology cultivated in the SPEEDER series, 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 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 common feeling of unreliability in the swing and lack of power at impact often associated with softer shafts is resolved by VTC technology. It optimally controls shaft torsion, efficiently transferring the energy from the shaft's snap-back 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, 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 for increased distance. The \"two-stage acceleration sensation\" that was unobtainable with previous shafts will elevate your shots to the next level.\u003c\/p\u003e\u003cp\u003eSpecifications\u003c\/p\u003e\u003cp\u003eCommon Specifications\/Features\u003c\/p\u003e\u003cp\u003eProduct Length: 46.0 inches\u003c\/p\u003e\u003cp\u003eTip Diameter: 8.50mm\u003c\/p\u003e\u003cp\u003eBend Profile: Tip \/ Butt (Double Kick)\u003c\/p\u003e\u003cp\u003ePrice: 49,500 yen (tax included)\u003c\/p\u003e\u003cp\u003eTarget Audience: Those with inconsistent head speed \/ Those who want to hit effortlessly\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, emphasis on ease of swing)\u003c\/p\u003e\u003cp\u003eR Flex\u003c\/p\u003e\u003cp\u003eWeight: 44.5g\u003c\/p\u003e\u003cp\u003eTorque: 6.9\u003c\/p\u003e\u003cp\u003eButt Diameter: 14.75mm\u003c\/p\u003e\u003cp\u003eS Flex\u003c\/p\u003e\u003cp\u003eWeight: 45.5g\u003c\/p\u003e\u003cp\u003eTorque: 6.9\u003c\/p\u003e\u003cp\u003eButt 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 (All-around, emphasis on balance)\u003c\/p\u003e\u003cp\u003eR Flex\u003c\/p\u003e\u003cp\u003eWeight: 54.0g\u003c\/p\u003e\u003cp\u003eTorque: 5.6\u003c\/p\u003e\u003cp\u003eButt Diameter: 14.85mm\u003c\/p\u003e\u003cp\u003eS Flex\u003c\/p\u003e\u003cp\u003eWeight: 55.0g\u003c\/p\u003e\u003cp\u003eTorque: 5.6\u003c\/p\u003e\u003cp\u003eButt Diameter: 14.90mm\u003c\/p\u003e\u003cp\u003e▶ If in doubt, choose this weight range.
