The only difference is the valve type: the \u003cstrong\u003eNr. 19-AP SV\u003c\/strong\u003e uses a Presta (SV) valve, while the \u003cstrong\u003eNr. 19-AP AV\u003c\/strong\u003e uses a Schrader (AV) valve. Choose based on your rim’s valve hole size — Presta valves require a narrower hole.\u003c\/p\u003e\u003ch4\u003eIs this tube compatible with both 28\" and 29\" wheels?\u003c\/h4\u003e\u003cp\u003eYes — 28\" and 29\" wheels share the same ETRTO rim diameter of 622 mm. The difference is in tyre width and marketing convention: 28\" is typically used for trekking and city bikes, while 29\" refers to mountain bike wheels. This tube fits both, as long as your tyre width falls between 40 and 62 mm.\u003c\/p\u003e\u003ch4\u003eWhat valve type does this tube use?\u003c\/h4\u003e\u003cp\u003eThe Nr. 19-AP SV uses a \u003cstrong\u003eSV (Sclavrand \/ Presta) valve\u003c\/strong\u003e with a 40 mm stem. Presta valves are narrower than Schrader valves and require a Presta-compatible pump head. They are standard on most road, trekking, and mountain bike rims with a smaller valve hole.\u003c\/p\u003e\u003ch4\u003eWhat makes the Air Plus better than a standard tube?\u003c\/h4\u003e\u003cp\u003eThe Air Plus is made with a higher proportion of pure butyl rubber and has walls approximately 70% thicker than a standard tube. This results in significantly better air retention (you pump up less often) and above-average resistance to punctures and pinch flats.\u003c\/p\u003e\u003ch4\u003eIs this tube compatible with e-bikes?\u003c\/h4\u003e\u003cp\u003eYes — the Air Plus tube is suitable for use in e-bike tyres within the compatible size range (28\"\/29\", 40–62mm). Its thicker walls make it a particularly good choice for heavier e-bikes where puncture resistance is important.\u003c\/p\u003e\u003ch4\u003eIs the Schwalbe Air Plus tube recyclable?\u003c\/h4\u003e\u003cp\u003eYes — like all Schwalbe tubes, the Air Plus Nr. 19-AP is 100% recyclable. Schwalbe runs a tube recycling programme, so when your tube reaches the end of its life, it can be returned for recycling rather than going to landfill.\u003c\/p\u003e","brand":"Schwalbe","offers":[{"title":"Default Title","offer_id":57204906361097,"sku":"1432833301","price":14.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0082\/4128\/3143\/files\/143_28_33301_4026495932707_1_png.webp?v=1784326415","url":"https:\/\/silverbackbikes.de\/products\/schwalbe-air-plus-inner-tube-nr-19-ap-28-29-sv-40mm-40-62-622-butyl","provider":"Silverback Bikes","version":"1.0","type":"link"}
