It is the exact series of masts and construction that our race team is using, and this Ultra High Modulus mast range is nothing short of spectacular! Drawing upon over a decade of experience in designing some of the most successful masts for foiling, we’ve brought this exceptional design to the market. Our innovative tab and flange connection system revolutionizes the way masts connect to fuselages. With a simple arrangement of just 3 M6 screws, we achieve a remarkably stable and galvanic corrosion-resistant connection. But that’s not all – we’ve obsessively optimized this connection to minimize drag, ensuring top-notch performance, stiffness and direct feedback from the foil. Please note that as we transition the graphic design of the new production, some mast will still have the standard GP graphics on them even though they are full TE construction.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"kitepuertorico","offers":[{"title":"75","offer_id":42458895220802,"sku":null,"price":1513.0,"currency_code":"USD","in_stock":true},{"title":"85","offer_id":42458895253570,"sku":null,"price":1679.0,"currency_code":"USD","in_stock":true},{"title":"95","offer_id":42458895286338,"sku":null,"price":1760.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0017\/6124\/7298\/files\/Platemast75_TE.webp?v=1758150301"},{"product_id":"f4-gp-plate-mast-te-copy","title":"F4 Foils GP Skinny AX Mast","description":"\u003cdiv\u003e\n\u003cp\u003eUHM 11mm MAST!\u003c\/p\u003e\n\u003cp\u003eCurrently in stock ready to ship: 80AX 85AX\u003cbr\u003eupdated July 6th\u003c\/p\u003e\n\u003cp\u003e75AX available in 3 weeks \u003c\/p\u003e\n\u003cp\u003eThe F4 AX Downwind Masts bring world-cup carbon engineering into your downwind and surf sessions.
