Shortening the shaft significantly improves the probability of a solid strike and increases straight-line accuracy, but it also has drawbacks such as a change in swing feel, increased shaft stiffness, and difficulty getting the ball airborne. The Speeder SLK utilizes the latest technology to overcome these disadvantages.\u003c\/p\u003e\u003cp\u003eFirst, by adopting Metal Composite Technology (MCT), which combines carbon and metal, a typical club balance can be achieved even with a standard head weight (around 200g). This allows for a consistent swing feel even with a shorter shaft and enables a higher center of gravity without increasing tip stiffness.\u003c\/p\u003e\u003cp\u003eAdditionally, by utilizing multi-hoop ply laminating technology, multiple hoop layers are laminated in the butt section to make it easier to feel the shaft's movement. This allows for a strong kick at the tip without making it feel stiff. Furthermore, a high-torque design ensures that the torque is not too tight, leading to good ball capture.\u003c\/p\u003e\u003cp\u003eTo address the decrease in launch height and clubhead speed due to shaft shortening, the vibration frequency is set to be softer. This enables a high trajectory and stable shots. Moreover, the larger diameter of the grip section prevents excessive force from being applied by the right hand, providing a natural swing feel.\u003c\/p\u003e\u003cp\u003eThe Speeder SLK is a golf shaft designed to maintain the light swing feel of the Speeder series while maximizing the benefits of shaft shortening.\u003c\/p\u003e\u003cp\u003e＜Specs＞\u003c\/p\u003e\u003cp\u003eSPD SLK 4\u003c\/p\u003e\u003cp\u003eR-Flex:\u003c\/p\u003e\u003cp\u003eWeight: 46.5g\u003c\/p\u003e\u003cp\u003eTorque: 7.2°\u003c\/p\u003e\u003cp\u003eButt Dia: 15.10mm\u003c\/p\u003e\u003cp\u003eS-Flex:\u003c\/p\u003e\u003cp\u003eWeight: 48.5g\u003c\/p\u003e\u003cp\u003eTorque: 7.1°\u003c\/p\u003e\u003cp\u003eButt Dia: 15.20mm\u003c\/p\u003e\u003cp\u003eCommon Specifications:\u003c\/p\u003e\u003cp\u003eKick Point: Mid\u003c\/p\u003e\u003cp\u003eLength: 45 inches\u003c\/p\u003e\u003cp\u003eTip Dia: 8.5mm\u003c\/p\u003e\u003cp\u003eSPD SLK 5\u003c\/p\u003e\u003cp\u003eR-Flex:\u003c\/p\u003e\u003cp\u003eWeight: 56.5g\u003c\/p\u003e\u003cp\u003eTorque: 6.1°\u003c\/p\u003e\u003cp\u003eButt Dia: 15.40mm\u003c\/p\u003e\u003cp\u003eS-Flex:\u003c\/p\u003e\u003cp\u003eWeight: 58.5g\u003c\/p\u003e\u003cp\u003eTorque: 6.0°\u003c\/p\u003e\u003cp\u003eButt Dia: 15.45mm\u003c\/p\u003e\u003cp\u003eX-Flex:\u003c\/p\u003e\u003cp\u003eWeight: 62.0g\u003c\/p\u003e\u003cp\u003eTorque: 5.9°\u003c\/p\u003e\u003cp\u003eButt Dia: 15.50mm\u003c\/p\u003e\u003cp\u003eCommon Specifications:\u003c\/p\u003e\u003cp\u003eKick Point: Mid\u003c\/p\u003e\u003cp\u003eLength: 45 inches\u003c\/p\u003e\u003cp\u003eTip Dia: 8.5mm\u003c\/p\u003e\u003cp\u003eSPD SLK 6\u003c\/p\u003e\u003cp\u003eS-Flex:\u003c\/p\u003e\u003cp\u003eWeight: 66.5g\u003c\/p\u003e\u003cp\u003eTorque: 5.1°\u003c\/p\u003e\u003cp\u003eButt Dia: 15.55mm\u003c\/p\u003e\u003cp\u003eX-Flex:\u003c\/p\u003e\u003cp\u003eWeight: 71.0g\u003c\/p\u003e\u003cp\u003eTorque: 5.0°\u003c\/p\u003e\u003cp\u003eButt Dia: 15.60mm\u003c\/p\u003e\u003cp\u003eCommon Specifications:\u003c\/p\u003e\u003cp\u003eKick Point: Mid\u003c\/p\u003e\u003cp\u003eLength: 45 inches\u003c\/p\u003e\u003cp\u003eTip Dia: 8.5mm\u003c\/p\u003e\u003cp\u003e＜Key Features＞\u003c\/p\u003e\u003cp\u003eFujikura\u003c\/p\u003e\u003cp\u003eSpeeder SLK\u003c\/p\u003e\u003cp\u003eGolf Shaft\u003c\/p\u003e\u003cp\u003eShortening\u003c\/p\u003e\u003cp\u003eImproved Strike Probability\u003c\/p\u003e\u003cp\u003eImproved Straightness\u003c\/p\u003e\u003cp\u003eMetal Composite Technology\u003c\/p\u003e\u003cp\u003eMulti-Hoop Ply Lamination\u003c\/p\u003e\u003cp\u003eHigh Torque Design\u003c\/p\u003e\u003cp\u003eHigh Trajectory\u003c\/p\u003e\u003cp\u003eStability\u003c\/p\u003e\u003cp\u003eSwing Feel\u003c\/p\u003e\u003cp\u003eGolf Club\u003c\/p\u003e\u003cp\u003eGraphite Shaft\u003c\/p\u003e\u003cp\u003eIncreased Distance\u003c\/p\u003e","brand":"アップサイドゴルフ本店","offers":[{"title":"5 \/ X","offer_id":49937588388069,"sku":"20022108","price":35200.0,"currency_code":"JPY","in_stock":true},{"title":"6 \/ R","offer_id":49937588420837,"sku":"20012152","price":35200.0,"currency_code":"JPY","in_stock":false},{"title":"4 \/ X","offer_id":49937588453605,"sku":"2002274","price":35200.0,"currency_code":"JPY","in_stock":false},{"title":"5 \/ S","offer_id":49937588486373,"sku":"20016108","price":35200.0,"currency_code":"JPY","in_stock":false},{"title":"6 \/ X","offer_id":49937588519141,"sku":"20022152","price":35200.0,"currency_code":"JPY","in_stock":false},{"title":"4 \/ R","offer_id":49937588551909,"sku":"2001274","price":35200.0,"currency_code":"JPY","in_stock":true},{"title":"6 \/ S","offer_id":49937588584677,"sku":"20016152","price":35200.0,"currency_code":"JPY","in_stock":true},{"title":"5 \/ R","offer_id":49937588617445,"sku":"20012108","price":35200.0,"currency_code":"JPY","in_stock":true},{"title":"4 \/ S","offer_id":49937588650213,"sku":"2001674","price":35200.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/0407\/0885\/files\/fuji-spdslk-prn-1_a1e07683-5550-4d86-a1b9-229a461ce32e.jpg?v=1785014349","url":"https:\/\/upsidegolf.co.jp\/en\/products\/fuji-spdslk-prn","provider":"UpsideGolf","version":"1.0","type":"link"}
