The \u003cstrong\u003eOPTIS (Odyssey Pneumatic Tire Insert System)\u003c\/strong\u003e relies on an independent inflatable insert, fitted inside the tyre and kept 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 for improved grip and comfort on rough terrain, while maintaining excellent support thanks to the high-pressure insert. Odyssey recommends as a starting point 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 indicates 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 pinch flats and rim damage. Its pressure also helps keep the tyre beads firmly against the rim, significantly limiting \u003cstrong\u003eburping\u003c\/strong\u003e and air loss under hard cornering. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn the event of a puncture resulting in a complete loss of tyre pressure, the insert temporarily continues to \u003cstrong\u003ekeep the tyre seated on the rim\u003c\/strong\u003e. This run-flat function is designed to give the rider greater control while slowing down and coming to a stop; Odyssey specifies that it should not be seen as a way to continue riding normally on a deflated 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":57418900439420,"sku":"PBS_ODYS079055","price":39.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/3444\/9318\/files\/ODSY-Optis_Insert-275-web_2048x2048_3f53390e-51db-41bc-8ee2-b396ed268b8d.webp?v=1788938196","url":"https:\/\/probikeshop-irl.com\/products\/odyssey-optis-27-5-anti-pinch-flat-tyre-insert-without-valve","provider":"Probikeshop","version":"1.0","type":"link"}
