The rear vent is the exhaust, and it is the half of the ventilation system riders forget. Without an outlet an intake achieves very little: it is the low-pressure region behind the helmet that actually pulls warm air out through the EPS channels. It sits where you cannot see damage, so it tends to be discovered broken rather than noticed breaking.\u003c\/p\u003e\n\n\u003cp\u003eVent covers are the cheapest thing on a helmet to break and among the most annoying to live without. A missing slider means a vent stuck open in winter or shut in summer; a cracked housing whistles at speed. Neither justifies a new helmet, and neither has to be tolerated.\u003c\/p\u003e\n\n\u003cp\u003eMatch the finish to your shell before ordering — dark grey belongs to the Spectrum colourway, and against a different finish it will read as the wrong colour in daylight. Fitting takes a couple of minutes and a screwdriver, and one part number covers both shell sizes.\u003c\/p\u003e\n\n\u003ch3\u003eFits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLS2 FF901 Advant X\u003c\/li\u003e\n\u003cli\u003eLS2 FF901 Advant X Carbon\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003ePosition\u003c\/em\u003e — rear exhaust\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFinish\u003c\/em\u003e — Dark Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMatches\u003c\/em\u003e — Spectrum\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFits\u003c\/em\u003e — all sizes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart number\u003c\/em\u003e — 800901AVR04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LS2","offers":[{"title":"Default Title","offer_id":53577374040330,"sku":"800901AVR04","price":12.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/800901AVR04_00.png?v=1787836303","url":"https:\/\/inter-pace.com\/en-va\/products\/ls2-ff901-advant-x-rear-air-vent-dark-grey","provider":"Inter-Pace","version":"1.0","type":"link"}
