Part number 8200324-1363-XL identifies this Carbon\/Red\/White helmet in XL sizing. Its outer shell uses a multi-composite structure with a 3K high-density carbon outer layer, uni-directional carbon composite, aramid fiber, and fiberglass bonded with epoxy resin. This pre-preg construction precisely controls the resin-to-fiber ratio to support high strength, efficient energy dissipation, reduced shell deflection, and improved energy management through the EPS liner.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eOuter Shell: Multi-composite shell combines 3K high-density carbon, uni-directional carbon composite, aramid fiber, and fiberglass for strength, lightweight performance, and controlled energy dissipation.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImpact Protection: Eight-piece multi-density EPS liner uses six strategically positioned densities to absorb impact forces and support a secure, comfortable fit.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFit System: A-Head Fitment System adjusts the helmet’s height and fore-aft angle to help riders achieve a personalized position and improved protective performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOblique Impact Management: Smooth, specially coated EPS surfaces create a low-friction interface that allows the comfort liner to move independently during oblique impacts, helping reduce transmitted forces.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAerodynamics: CFD simulations, wind-tunnel testing, and track validation support low-drag performance and aerodynamic stability.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRace Spoilers: Includes standard and extended race spoilers with elastic joints designed to detach during significant impacts to help reduce rotational energy.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLateral Stability: Winglets support aerodynamic stability and help improve drag performance at speed.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVisor Design: Integrated turbulators improve aero-acoustic performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVentilation: Eleven ventilation points, including seven intakes and four exhausts, provide airflow through channels integrated with the EPS liner.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eChin Ventilation: Front chin vents direct air toward the shield to help prevent fogging while also allowing humid air to escape.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eTop Ventilation: A large central slider channels air toward the crown and provides forehead heat extraction when open.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRear Exhausts: Two extractor vents beneath the rear spoiler help remove hot air from inside the helmet.\u003c\/li\u003e\u003c\/ul\u003e","brand":"ALPINESTARS","offers":[{"title":"Default Title","offer_id":49349893030123,"sku":"010116991","price":1379.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/3882\/9547\/files\/2964564.png?v=1788593491","url":"https:\/\/ctracingservices.com\/products\/alpinestars-supertech-r10-element-carbon-red-white-helmet-xl-8200324-1363-xl","provider":"Cascade Tire \u0026 Racing Services","version":"1.0","type":"link"}
