The base material is therefore sieved at enormous pressure through seven filters before being extruded. All tubes are inserted into a mould and inflated for vulcanization to ensure constant wall thickness and high air pressure retention.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReliability.\u003c\/strong\u003e All tubes are inflated and stored for 24 hours in order to test for air pressure retention. Afterwards each, individual tube undergoes a careful visual inspection. This special quality control helps prevent unpleasant surprises and is why, over many years, Schwalbe tubes have become highly respected for outstanding reliability by bicycle dealers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGroup tube system.\u003c\/strong\u003e Only high elasticity and good quality allows a tube to cover very many tire sizes. Tube No. 18 can fit tire widths between 28 mm and 44 mm and that is a big advantage to the trade and simultaneously it vouches for the tube's quality. Only an extremely high-quality and reliable tube is up to to this requirement.\u003c\/p\u003e\n\u003cstrong\u003eValve.\u003c\/strong\u003e All valves are nickel plated and threaded and valve inserts are replaceable. Also Schwalbe tubes with the classic bicycle valve are capable of pressure testing thanks to a high pressure valve seal. And it is plain to see as each tube is crowned with a transparent polycarbonate dust cap.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan id=\"product_description\" itemprop=\"description\"\u003eThink you got a defective Schwalbe tube or tire? \u003ca href=\"http:\/\/www.schwalbetires.com\/company\/warranty_policy\" target=\"_blank\"\u003e Click here.\u003c\/a\u003e\u003c\/span\u003e \u003cbr\u003e\u003cbr\u003e\u003cobject height=\"340\" width=\"560\"\u003e\u003cparam name=\"movie\" value=\"http:\/\/www.youtube.com\/v\/TkNyN0j_cfo?fs=1\u0026amp;hl=en_US\"\u003e\n\u003cparam name=\"allowFullScreen\" value=\"true\"\u003e\n\u003cparam name=\"allowscriptaccess\" value=\"always\"\u003e\n\u003cembed src=\"\/\/www.youtube.com\/v\/TkNyN0j_cfo?fs=1\u0026amp;hl=en_US\" type=\"application\/x-shockwave-flash\" allowscriptaccess=\"always\" allowfullscreen=\"true\" width=\"560\" height=\"340\"\u003e\u003c\/object\u003e","brand":"Schwalbe Tires North America Inc (566)","offers":[{"title":"Default Title","offer_id":23337566081,"sku":"TU-B","price":10.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1403\/7343\/products\/tu-bsv12.jpg?v=1615409604","url":"https:\/\/www.rivbike.mom\/products\/schwalbe-sv12-inner-tube-650b-x-32-47-26-x-1-25-1-75-10066","provider":"Rivendell Bicycle Works","version":"1.0","type":"link"}
