The Spartan RS is built with a high-strength multiaxial fiberglass composite shell paired with a multi-density EPS inner liner. This sophisticated multi-composite layout absorbs and diffuses heavy impact forces with progressive efficiency while keeping the overall structure lightweight. To ensure a sleek, tailored profile across all sizes, the exterior architecture is scaled across two distinct shell configurations.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eAerodynamic performance is hardcoded into the distinct lines of the Spartan RS. The outer shell profile has been meticulously refined through Computational Fluid Dynamics (CDFD) wind-tunnel simulation to cut through the air seamlessly, significantly reducing drag, eliminating high-speed head buffeting, and isolating external ear noise. The ventilation system provides targeted climate control, using three front intakes to push fresh air directly into internal cooling channels while hot air is extracted through four rear venturi-effect spoiler outlets.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eThe helmet is equipped with the high-performance VZ 300 Optical Class 1 visor, utilizing variable thicknesses to provide zero visual distortion at any viewing angle. For absolute track-inspired security, the main visor features an ultra-robust 4-point anchor locking mechanism derived from Shark's flagship racing helmets, paired with an included Pinlock 120 Max Vision anti-fog insert. Complete with an internal UV380 drop-down sun visor, a plush Alveotech Sanitized-treated moisture-wicking lining, an EasyFit system for glasses wearers, and a secure double D-ring chin strap, trust On Yer Bike to elevate your journey with the Shark Spartan RS Byhron.\u003c\/p\u003e","brand":"Shark","offers":[{"title":"X Small","offer_id":54002863538503,"sku":"HE8111E\/KOU XS","price":319.99,"currency_code":"GBP","in_stock":true},{"title":"Small","offer_id":54002863571271,"sku":"HE8111E\/KOU S","price":199.99,"currency_code":"GBP","in_stock":true},{"title":"Medium","offer_id":54002863604039,"sku":"HE8111E\/KOU M","price":199.99,"currency_code":"GBP","in_stock":true},{"title":"Large","offer_id":54002863636807,"sku":"HE8111E\/KOU L","price":319.99,"currency_code":"GBP","in_stock":true},{"title":"X Large","offer_id":54002863669575,"sku":"HE8111E\/KOU XL","price":319.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0854\/8928\/7495\/files\/stock71265_1.jpg?v=1779805425","url":"https:\/\/shop.onyerbike.net\/products\/shark-spartan-rs-byhron-helmet-matt-black","provider":"On Yer Bike","version":"1.0","type":"link"}
