Tire assemblies are one of the most important performance factors for any bike. They provide all the grip to the ground, they serve as a critical first element of the bike’s suspension and they provide essential support to the cornering forces that the bike encounters. Pressure choice is always a compromise to balance these requirements.\u003c\/p\u003e\n\u003cp\u003eAvailable in 27.5\" or 29\" sizes with a standard length OPTIS valve or a longer OPTIS valve (ETA TBD) for taller carbon rims. Replacement inserts also available separately (OPTIS valve needed).\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eWhy use\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eOPTIS\u003c\/strong\u003e?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOPTIS prevents tire burping\u003c\/strong\u003e. By pressing the tire against the rim and preventing gaps from opening, burping becomes almost impossible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOPTIS allows for lower tire pressures\u003c\/strong\u003e. The insert is inflated to a higher pressure than the tire, keeping the tire supported while allowing the main volume to be at a lower pressure that provides optimum grip.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOPTIS protects the rim and tire against impacts\u003c\/strong\u003e. The insert’s higher pressure provides protection against impacts, reducing the chances of tire pinching and rim damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOPTIS locks the tire bead and provides a temporary run-flat period if the tire is damaged\u003c\/strong\u003e. OPTIS will securely hold the tire to the rim for a short period of time if the tire is ever critically damaged and loses its air. This can allow for a brief run-flat period that gives the rider more control than they would otherwise have, providing the time needed to stop the bicycle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOPTIS is lightweight.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eWheel assemblies using OPTIS are significantly lighter than most of the alternative tubeless insert set-ups, while also providing greater protection. The OPTIS insert’s bead locking feature and tire support can also allow for lighter than typical tire and rim choices, resulting in overall weight savings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOPTIS installation is easy and helps to seat tires.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUnlike foam inserts, OPTIS installs as easily as a traditional inner tube, and inflation starts the process of pushing the tire beads outward to ease tire inflation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOPTIS allows for low rolling resistance.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBy facilitating the use of lower pressures and lighter tires, rolling efficiency on rough surfaces is greatly improved.\u003c\/p\u003e","brand":"Odyssey","offers":[{"title":"27.5\"","offer_id":46933798584512,"sku":null,"price":126.0,"currency_code":"SGD","in_stock":true},{"title":"29\"","offer_id":46933798617280,"sku":null,"price":126.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0503\/8548\/6016\/files\/ODSY-OPTISInset1-Web_2048x2048_1d6bfad9-ca6a-48ca-90a2-647f4fec11a5.jpg?v=1760070248","url":"https:\/\/unspokin.mom\/en-cn\/products\/odyssey","provider":"Unspokin","version":"1.0","type":"link"}
