Check the sidewall of your tyre for the ETRTO code — if the first number is between 40 and 62, and the second number is 584, 622, or 635, this tube fits.\u003c\/p\u003e\u003ch3\u003eWhat valve type does this tube use?\u003c\/h3\u003e\u003cp\u003eThe No. 19 uses a \u003cstrong\u003eSchrader valve (AV – Auto Valve)\u003c\/strong\u003e with a 40 mm stem. Schrader valves are the same type found on car tyres and are compatible with any standard pump, including petrol station air compressors. No adapter needed.\u003c\/p\u003e\u003ch3\u003eIs this tube suitable for MTB use?\u003c\/h3\u003e\u003cp\u003eYes. The No. 19 is specifically designed for the wide tyre widths (40–62 mm) common on MTB, gravel, and trekking bikes. Its robust butyl construction handles the stresses of off-road riding and varied terrain well.\u003c\/p\u003e\u003ch3\u003eHow do I know if this tube fits my bike?\u003c\/h3\u003e\u003cp\u003eCheck the sidewall of your tyre for two numbers, e.g. \u003cem\u003e50-584\u003c\/em\u003e or \u003cem\u003e57-622\u003c\/em\u003e. The first number is the tyre width in mm (must be between 40–62), and the second is the rim diameter (must be 584, 622, or 635). If both match, the No. 19 is your tube.\u003c\/p\u003e\u003ch3\u003eWhat is the difference between a Schrader (AV) and Presta (SV) valve?\u003c\/h3\u003e\u003cp\u003eA \u003cstrong\u003eSchrader valve\u003c\/strong\u003e is wider, has a spring-loaded pin, and is compatible with all standard pumps including car pumps. A \u003cstrong\u003ePresta valve\u003c\/strong\u003e is narrower, lighter, and requires a Presta-specific pump head. Check your rim's valve hole size before purchasing — Schrader holes are wider (~8 mm) and cannot be used with Presta tubes without an adapter.\u003c\/p\u003e\u003ch3\u003eWhy is butyl rubber the preferred material for inner tubes?\u003c\/h3\u003e\u003cp\u003eButyl rubber offers \u003cstrong\u003eexcellent air retention\u003c\/strong\u003e, meaning you'll need to top up pressure far less often than with latex tubes. It's also more durable, more puncture-resistant, and more affordable. For everyday riding, commuting, and touring, butyl is the industry standard.\u003c\/p\u003e\u003ch3\u003eHow do I install the Schwalbe Tube No. 19?\u003c\/h3\u003e\u003cp\u003e1. Remove the wheel and fully deflate the tyre. 2. Use tyre levers to unseat one bead of the tyre from the rim. 3. Remove the old tube. 4. Lightly inflate the new tube to give it shape. 5. Insert the Schrader valve through the rim hole and tuck the tube evenly inside the tyre. 6. Reseat the tyre bead by hand — avoid metal levers on the final bead to prevent pinching. 7. Inflate to the pressure recommended on your tyre sidewall.\u003c\/p\u003e\u003ch3\u003eWhat inflation pressure should I use?\u003c\/h3\u003e\u003cp\u003eAlways follow the \u003cstrong\u003emin\/max pressure printed on your tyre sidewall\u003c\/strong\u003e, not the tube. For wide MTB and trekking tyres (40–62 mm), typical pressures range from \u003cstrong\u003e2.0–4.5 bar (30–65 PSI)\u003c\/strong\u003e. Lower pressures improve grip and comfort on rough terrain; higher pressures reduce rolling resistance on smooth surfaces.\u003c\/p\u003e\u003ch3\u003eIs this tube sold individually or in a pack?\u003c\/h3\u003e\u003cp\u003eThis listing is for \u003cstrong\u003eone (1) tube\u003c\/strong\u003e. Trade cartons contain 25 units (VE: 25).\u003c\/p\u003e\u003ch3\u003eWhat is the difference between Schwalbe Tube No. 19 and No. 19 AP (Air Plus)?\u003c\/h3\u003e\u003cp\u003eThe standard No. 19 uses conventional butyl rubber. The \u003cstrong\u003eAir Plus (AP)\u003c\/strong\u003e version features a thicker butyl wall for enhanced puncture resistance and even longer air retention — ideal for loaded touring, bikepacking, or urban riders who want maximum reliability between maintenance checks.\u003c\/p\u003e","brand":"Schwalbe","offers":[{"title":"Default Title","offer_id":57205752529161,"sku":"1432821005","price":10.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0082\/4128\/3143\/files\/143_28_21005_4026495929387_1_png.webp?v=1784385058","url":"https:\/\/silverbackbikes.de\/products\/schwalbe-tube-no-19-27-5-28-29-av-40mm-40-62-584-635-butyl","provider":"Silverback Bikes","version":"1.0","type":"link"}
