Always check your rim’s ETRTO diameter before ordering.\u003c\/p\u003e\u003ch4\u003eWhat valve type does this tube use?\u003c\/h4\u003e\u003cp\u003eThe Nr. 17-AP uses an \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 common on road, trekking, and city 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 — ideal for daily commuters who can’t afford a flat.\u003c\/p\u003e\u003ch4\u003eIs this tube suitable for city and trekking bikes?\u003c\/h4\u003e\u003cp\u003eYes — the Nr. 17-AP is an excellent choice for 28\" city bikes, trekking bikes, and touring bikes running tyres between 37 and 47 mm wide. Its superior air retention and puncture resistance make it particularly well-suited to everyday riding where reliability matters most.\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\", 37–47mm). 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. 17-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":57204894040329,"sku":"1432831601","price":14.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0082\/4128\/3143\/files\/143_28_31601_4026495932424_1_png.webp?v=1784324693","url":"https:\/\/silverbackbikes.de\/de\/products\/schwalbe-air-plus-inner-tube-nr-17-ap-28-sv-40mm-37-47-622-635-butyl","provider":"Silverback Bikes","version":"1.0","type":"link"}
