GR501 DR and GR601 DR are heavy shafts that produce overwhelming initial ball speed by combining \"weight\" and \"repulsive force.\"\u003c\/p\u003e\u003cp\u003eTheir design concept is \"ultra-fast repulsion.\" The double counter design, which optimally distributes weight to the grip and tip, and the unique long straight structure, which places the center of gravity and kick point at the same position, accelerate the shaft's snapback.\u003c\/p\u003e\u003cp\u003eUltra-high modulus material is layered at the tip, significantly improving repulsion performance upon impact. Furthermore, the semi-flat flex design enhances stability during the swing and increases the sweet spot hit rate for athlete-oriented golfers.\u003c\/p\u003e\u003cp\u003eFrom drivers to wedges, the oscillation frequency is unified with a gentle flow design. This allows for swinging every club at the same tempo, stabilizing the swing rhythm and improving shot accuracy throughout the course.\u003c\/p\u003e\u003cp\u003eThe GR501 is for mid-head speed players, and the GR601 is for hard hitters, allowing selection based on playing style. With this model, packed with WACCINE COMPO. series technology, let's redefine the conventional wisdom of speed and distance.\u003c\/p\u003e\u003cp\u003e\u003cspecifications\u003e\u003c\/specifications\u003e\u003c\/p\u003e\u003cp\u003eGR501 Specifications\u003c\/p\u003e\u003cp\u003eDriver (DR)\u003c\/p\u003e\u003cp\u003eFlex: DR (equivalent to S)\u003c\/p\u003e\u003cp\u003eH\/S Suitability: 40-45m\/s\u003c\/p\u003e\u003cp\u003eWeight: 56g\u003c\/p\u003e\u003cp\u003eKick Point (K.P.): Mid\u003c\/p\u003e\u003cp\u003eTorque: 3.8\u003c\/p\u003e\u003cp\u003eCPM: 245cpm\u003c\/p\u003e\u003cp\u003eProduct Length: 1181mm\u003c\/p\u003e\u003cp\u003eTip Diameter: 8.6mm\u003c\/p\u003e\u003cp\u003eG.C.L (Center of Gravity Position from Grip): 53%\u003c\/p\u003e\u003cp\u003eReference values for X flex (X(*))\u003c\/p\u003e\u003cp\u003eH\/S Suitability: 46-50m\/s\u003c\/p\u003e\u003cp\u003eWeight: 57g\u003c\/p\u003e\u003cp\u003eTorque: 3.6\u003c\/p\u003e\u003cp\u003eCPM: 260cpm\u003c\/p\u003e\u003cp\u003eGR601 Specifications\u003c\/p\u003e\u003cp\u003eDriver (DR):\u003c\/p\u003e\u003cp\u003eFlex: DR (equivalent to S)\u003c\/p\u003e\u003cp\u003eH\/S Suitability: 40-45m\/s\u003c\/p\u003e\u003cp\u003eWeight: 63g\u003c\/p\u003e\u003cp\u003eKick Point: Mid\u003c\/p\u003e\u003cp\u003eTorque: 3.6\u003c\/p\u003e\u003cp\u003eCPM: 245cpm\u003c\/p\u003e\u003cp\u003eProduct Length: 1181mm\u003c\/p\u003e\u003cp\u003eTip Diameter: 8.6mm\u003c\/p\u003e\u003cp\u003eG.C.L: 53%\u003c\/p\u003e\u003cp\u003eReference values for X flex (X(*))\u003c\/p\u003e\u003cp\u003eH\/S Suitability: 46-50m\/s\u003c\/p\u003e\u003cp\u003eWeight: 65g\u003c\/p\u003e\u003cp\u003eTorque: 3.4\u003c\/p\u003e\u003cp\u003eCPM: 260cpm\u003c\/p\u003e\u003cp\u003e\u003cpoints\u003e\u003c\/points\u003e\u003c\/p\u003e\u003cp\u003eWaccine Compo\u003c\/p\u003e\u003cp\u003eWACCINE COMPO\u003c\/p\u003e\u003cp\u003eGR501 Shaft\u003c\/p\u003e\u003cp\u003eGR601 Golf Shaft\u003c\/p\u003e\u003cp\u003eGolf Distance Improvement\u003c\/p\u003e\u003cp\u003eHeavy Golf Shaft\u003c\/p\u003e\u003cp\u003eDouble Counter Design\u003c\/p\u003e\u003cp\u003eLong Straight Shaft\u003c\/p\u003e\u003cp\u003eUltra-Fast Repulsion Shaft\u003c\/p\u003e\u003cp\u003eIncreased Initial Ball Speed Driver\u003c\/p\u003e\u003cp\u003eHigh Sweet Spot Hit Rate Shaft\u003c\/p\u003e\u003cp\u003eFor Athlete Golfers\u003c\/p\u003e\u003cp\u003ePopular Golf Shaft Model\u003c\/p\u003e\u003cp\u003eHeavy Balance Shaft\u003c\/p\u003e\u003cp\u003eHigh Modulus Material Shaft\u003c\/p\u003e\u003cp\u003eFrom Driver to Iron\u003c\/p\u003e\n","brand":"アップサイドゴルフ本店","offers":[{"title":"Doctor (X) \/ GR601","offer_id":49941893447909,"sku":"10022002","price":88000.0,"currency_code":"JPY","in_stock":true},{"title":"DR \/ GR601","offer_id":49941893480677,"sku":"10022001","price":88000.0,"currency_code":"JPY","in_stock":true},{"title":"Doctor (X) \/ GR501","offer_id":49941893513445,"sku":"10012002","price":88000.0,"currency_code":"JPY","in_stock":true},{"title":"DR \/ GR501","offer_id":49941893546213,"sku":"10012001","price":88000.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/0407\/0885\/files\/wac-gr5601dr-cob-1.jpg?v=1783210509","url":"https:\/\/upsidegolf.co.jp\/en\/products\/wac-gr5601dr-cob","provider":"UpsideGolf","version":"1.0","type":"link"}
