{"product_id":"chinook-1-bolt-pro-flex-mast-base-us-cup-2022","title":"Chinook 1-Bolt Pro Flex Mast Base - US Cup 2022","description":"The Chinook 1-Bolt Pro Flex Mast Base combines tendon and mechanical base technology for superior foiling performance. Featuring a shorter Proflex Chinook Tendon, this base delivers easy serviceability and a free-moving mechanical hinge that accommodates larger or wider foil boards, formula boards, and long boards with effortless attachment. The mechanical hinge reduces fatigue by an estimated 75-80% compared to traditional tendon-only designs, while the foil board design minimizes flip-over risk during attachment and water starts. Crafted from durable cast 316 stainless steel with a polished finish, this base is built to last. Specifically engineered for foiling—not recommended for bump and jump, slalom, or formula racing. Available in 1-Bolt, 2-Bolt Euro-Pin, and US Base Cup configurations.","brand":"Chinook","offers":[{"title":"Default Title","offer_id":45413974573090,"sku":null,"price":108.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0876\/5646\/4418\/files\/50F-One-BoltProflexMastBaseUS_1600x_png.webp?v=1782928631","url":"https:\/\/larsonsport.com\/products\/chinook-1-bolt-pro-flex-mast-base-us-cup-2022","provider":"Larson's Ski \u0026 Sport","version":"1.0","type":"link"}
