Designed to offer a mast for every rider, discipline and condition, it pushes the boundaries of carbon construction highlighted by Armstrong's refined 11.8 mm profile. As rider expectations continue to evolve, this range delivers the stiffness, efficiency and control needed to perform and progress at every level.\u003c\/p\u003e\n\u003cp\u003eThe Performance-X Carbon Mast 11.8 mm is a deliberate choice for riders who prioritise glide speed and refined turning feel over maximum stiffness. Ideal for downwind, fast winging and clean carving lines. 10% more torsional stiffness and 10% more bending stiffness than the outgoing Performance Mast generation.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eUltra-High Modulus carbon construction.\u003c\/strong\u003e Built from Ultra-High Modulus carbon, the Performance-X Mast 11.8 mm pushes the limit of what's possible in layer engineering.

Same 11.8 mm profile and A+ System, just less premium carbon.

If you're primarily downwinding, prone surfing in chop, or chasing wing foil top speed in clean conditions, go longer (865 or 935). If you're surfing reef breaks or want a compact setup, the 725 is the right choice.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWho is this for?\u003c\/strong\u003e Advanced riders who already know what they want from a mast. Riders who've spent time on a Performance MkII or earlier Performance carbon and are looking for the upgrade. Downwinders chasing speed and glide. Racers. Riders for whom the price tag isn't the limiting factor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWho isn't this for?\u003c\/strong\u003e First-time foilers (start with an Alloy or MkII Carbon). Riders prioritising absolute stiffness over efficiency (the Performance MkII is stiffer). Anyone who'd struggle to feel the difference between top-tier carbon masts — the gap to the Performance MkII is small and not worth the £500+ premium unless you specifically want what the PX offers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAbout this mast in North Wales.\u003c\/strong\u003e The PX excels in the long flatwater stretches around Red Wharf Bay and the Penmaenmawr side-shore wind — conditions where its efficiency advantage pays off. In typical Conwy Bay chop you'll feel the difference vs an alloy or MkII Carbon, but the gap to a Performance MkII is more subtle.

Armstrong's modular A+ System has set the industry standard for foil compatibility — front wings, masts, fuselages and stabilisers all interconnect across the Armstrong range, meaning riders can progress from S1 (Step 1) beginner foils through to HA (High Aspect) racing foils without replacing their mast or board fittings. Built in Thailand at Armstrong's own facility, designed in New Zealand, ridden by world-class athletes including Austin Tovey, Noah Flegel and Annie Reickert.\u003c\/p\u003e\n\u003cp\u003eMôr Watersports is an authorised Armstrong dealer in North Wales — we hold stock, offer demo sessions where conditions allow, and ship across the UK with free postage.\u003c\/p\u003e\n\n\u003cp\u003eFree UK postage. \u003cstrong\u003e01492 588001\u003c\/strong\u003e to talk through length choice, mast tier, or whether the Performance-X is the right next step for your foiling.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"725","offer_id":55563653677432,"sku":"PX725","price":2139.0,"currency_code":"GBP","in_stock":true},{"title":"795","offer_id":55563653710200,"sku":"PX795","price":2179.0,"currency_code":"GBP","in_stock":true},{"title":"865","offer_id":55563653742968,"sku":"PX865","price":2229.0,"currency_code":"GBP","in_stock":true},{"title":"935","offer_id":55563653775736,"sku":"PX935","price":2269.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/0653\/4457\/files\/Armstrong-PMX795-01.jpg?v=1779132859","url":"https:\/\/morwatersports.com\/products\/armstrong-performance-x-carbon-mast","provider":"Môr Watersports","version":"1.0","type":"link"}
