Its 48 mm Schrader valve has a removable core and a smooth, straight stem. Choose it as a replacement tube or a spare after checking the size printed on your tire and the valve opening in your rim.\u003c\/p\u003e\n\u003ch3\u003eHow to check the fit\u003c\/h3\u003e\u003cp\u003eThree details need to match: wheel diameter, tire width, and valve type. The 2.00–2.25 range is the tire width range this tube is intended to fit. ISO 406 identifies the wheel diameter standard; the familiar “20-inch” label alone is not enough because some similarly named wheel sizes use a different diameter.\u003c\/p\u003e\u003cp\u003eSchrader is the wider, car-style valve. This tube needs a rim drilled for Schrader and a pump head that accepts it. The 48 mm stem must extend far enough above your rim for the pump to grip.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSize: 20 × 2.00–2.25 inches\u003c\/li\u003e\n\u003cli\u003eWheel diameter standard: ISO 406\u003c\/li\u003e\n\u003cli\u003eValve: 48 mm Schrader, straight (0°), smooth stem\u003c\/li\u003e\n\u003cli\u003eRemovable valve core\u003c\/li\u003e\n\u003cli\u003eWall thickness: 0.9 mm\u003c\/li\u003e\n\u003cli\u003eFlat fold width: 51 mm\u003c\/li\u003e\n\u003cli\u003eSold individually: one inner tube\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWill this fit any 20-inch bicycle?\u003c\/strong\u003e Check the ISO diameter and tire width on the sidewall, then confirm the rim accepts a Schrader valve.
