The \u003cstrong\u003eNr. 14-AP SV\u003c\/strong\u003e fits narrower tyres (40–62 mm, ETRTO 40\/62-584). The \u003cstrong\u003eNr. 14L-AP SV\u003c\/strong\u003e fits wider tyres (54–70 mm, ETRTO 54\/70-584) and is also suitable for 27.5+ format. Choose based on your tyre’s width.\u003c\/p\u003e\u003ch4\u003eWhat is 27.5+ and is this tube compatible?\u003c\/h4\u003e\u003cp\u003e27.5+ (also called 650B+) refers to 27.5\" wheels fitted with extra-wide tyres, typically 2.8\" (70 mm) or wider. This tube (ETRTO 54\/70-584) covers tyres up to 70 mm wide, making it compatible with most 27.5+ setups. Always check your specific tyre’s ETRTO width before ordering.\u003c\/p\u003e\u003ch4\u003eWhat valve type does this tube use?\u003c\/h4\u003e\u003cp\u003eThe Nr. 14L-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 standard on most mountain bike and trail rims.\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 (27.5\" \/ 27.5+, 54–70mm). 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. 14L-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":57204891091209,"sku":"1432624021","price":14.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0082\/4128\/3143\/files\/143_26_24021_4026495933100_1_png.webp?v=1784324316","url":"https:\/\/silverbackbikes.de\/de\/products\/schwalbe-air-plus-inner-tube-nr-14l-ap-27-5-27-5-sv-40mm-54-70-584-butyl","provider":"Silverback Bikes","version":"1.0","type":"link"}
