The \u003cstrong\u003eOPTIS (Odyssey Pneumatic Tire Insert System)\u003c\/strong\u003e system relies on an independent inflatable insert, installed inside the tyre and maintained at a higher pressure than the tyre itself. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThis design allows you to \u003cstrong\u003elower tyre pressure\u003c\/strong\u003e to gain grip and comfort on rough terrain, while maintaining excellent support thanks to the high-pressure insert. As a starting point, Odyssey recommends reducing your usual tyre pressure by around \u003cstrong\u003e10%\u003c\/strong\u003e and inflating the OPTIS to around \u003cstrong\u003e25% above the desired tyre pressure\u003c\/strong\u003e. For off-road riding, the brand notes that a pressure reduction of around 15% can also be considered depending on the rider and terrain. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn the event of a heavy impact, the OPTIS also forms a \u003cstrong\u003epneumatic barrier between the tyre and the rim\u003c\/strong\u003e, reducing the risk of tyre pinch flats and rim damage. At the same time, its pressure helps keep the tyre beads firmly against the rim, significantly limiting \u003cstrong\u003eburping\u003c\/strong\u003e and air loss during aggressive cornering and high loads. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn the event of a puncture causing total tyre pressure loss, the insert temporarily continues to \u003cstrong\u003ehold the tyre on the rim\u003c\/strong\u003e. This Run-Flat function is designed to give the rider more control while slowing down and coming to a stop; Odyssey specifies that it should not be considered a way to continue riding normally on a flat tyre. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFinally, unlike many foam inserts, the OPTIS is installed in a similar way to a \u003cstrong\u003estandard inner tube\u003c\/strong\u003e. During inflation, the insert also pushes the tyre beads outwards, making them easier to seat on the rim. The system is available in \u003cstrong\u003e27.5\" and 29\"\u003c\/strong\u003e for MTB rims with an \u003cstrong\u003einternal width of 30 to 40 mm\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u0026nbsp;\u003c\/p\u003e","brand":"ODYSSEY","offers":[{"title":"Default Title","offer_id":57418900636028,"sku":"PBS_ODYS079054","price":89.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/3444\/9318\/files\/ODSY-OPTISchunk-Web_34b548de-1290-4129-98e7-50ce8837f3ea.webp?v=1788938280","url":"https:\/\/probikeshop-irl.com\/products\/odyssey-optis-anti-pinch-flat-insert-29-with-dual-valve","provider":"Probikeshop","version":"1.0","type":"link"}
