{"product_id":"chinook-2-bolt-pro-flex-mast-base-us-cup","title":"Chinook 2-Bolt Pro Flex Mast Base - US Cup","description":"The Chinook 2-Bolt Pro Flex Mast Base combines tendon and mechanical base advantages for superior performance. Engineered specifically for foiling, this US Cup version features a shorter Proflex Chinook Tendon for easy maintenance and a free-moving mechanical hinge that reduces fatigue by an estimated 75-80% compared to traditional designs.\n\nThe mechanical hinge simplifies attachment on larger boards, wider foil boards, and long boards while minimizing flip-over risk during waterstarting. Crafted from cast 316 stainless steel, it delivers exceptional durability with a distinctive polished steel finish.\n\nNote: Designed for foiling only. Not recommended for bump and jump, slalom, or formula racing. Warranty void if used for these applications.","brand":"Chinook","offers":[{"title":"Default Title","offer_id":45413974999074,"sku":null,"price":121.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0876\/5646\/4418\/files\/52F-Two-BoltProflexMastBaseUS_1600x_png.webp?v=1782936073","url":"https:\/\/larsonsport.com\/products\/chinook-2-bolt-pro-flex-mast-base-us-cup","provider":"Larson's Ski \u0026 Sport","version":"1.0","type":"link"}
