This WTB NanoAir fits 700c tires from 18 to 32 mm wide and uses an 85 mm Presta valve. It is the W015-0091 version, so you can match the exact size and valve before ordering.\u003c\/p\u003e\n\u003ch3\u003eA mechanic's explanation\u003c\/h3\u003e\n\u003cp\u003eThink of tube fit as two separate checks: the tube must fit the tire, and the valve must reach through the rim. The 700 × 18–32 mm marking identifies the wheel size and supported tire widths. The 85 mm measurement describes the valve stem, not the tire size. On a deeper rim, that longer stem helps leave enough valve exposed for a pump head to grip. Check your rim depth and pump-head clearance before choosing a valve length.\u003c\/p\u003e\n\u003cp\u003eTPU stands for thermoplastic polyurethane. Its practical appeal is a small packed size and low weight: it takes up less room in your repair kit than a conventional butyl spare. WTB lists this specific version at 39 g. A spare still needs to match your tire; a compact tube that is too narrow for your tire is the wrong spare.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e700c fit for tires 18–32 mm wide\u003c\/li\u003e\n\u003cli\u003e85 mm alloy Presta valve with a fixed, non-removable core\u003c\/li\u003e\n\u003cli\u003eLightweight TPU construction\u003c\/li\u003e\n\u003cli\u003eCompact format for a saddle bag, tool pouch, or jersey pocket\u003c\/li\u003e\n\u003cli\u003eTPU repair patches included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBrand \/ model\u003c\/th\u003e\n\u003ctd\u003eWTB NanoAir TPU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTire size\u003c\/th\u003e\n\u003ctd\u003e700 × 18–32 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eISO bead-seat diameter\u003c\/th\u003e\n\u003ctd\u003e622 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eThermoplastic polyurethane (TPU)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eValve\u003c\/th\u003e\n\u003ctd\u003e85 mm Presta; alloy; smooth shaft; fixed core\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eColor\u003c\/th\u003e\n\u003ctd\u003eTan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eManufacturer claimed weight\u003c\/th\u003e\n\u003ctd\u003e39 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eManufacturer part number\u003c\/th\u003e\n\u003ctd\u003eW015-0091\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eUPC\u003c\/th\u003e\n\u003ctd\u003e714401150911\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cp\u003eOne inner tube and two glue-less TPU patches.
