Not only is each individual tube\ninflated \u0026amp; inserted into a mould to ensure that there is even wall thickness \u0026amp;\nexcellent air retention, they are also stored under pressure for 24hrs to test\nair retention. Airtightness: Schwalbe tubes retain air pressure considerably\nlonger. The quality and the material purity of the rubber mixture directly\neffects the quality of the tube. Each Schwalbe tube is individually inflated\nand inserted into a mold. This ensures the even wall thickness and excellent\nair retention. Reliability: Consistent quality control brings with it the\nsecurity of use: Each tube is inflated at the factory and stored under\npressure for 24 hours in order to test the air retention. Group Tube System:\nThe high elasticity and quality material used in our tubes allows a great many\ntyre sizes to be covered. Only an extremely high-quality and reliable tube is\nup to this requirement. Retains pressure longer! In comparative tests against\nother tubes (including named brands, own-label brands and no name products).\nThe result was clear. Over a period of 30 days the other tubes lost nearly\ntwice as much pressure than Schwalbe tubes. Possible reasons: Less butyl\ncontent, or lower quality of of butyl. Schwalbe is uncompromising in its\nstandards, despite ever increasing world market prices of butyl.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eProven Schwalbe tubes for 650B wheels, on or off road\u003c\/li\u003e\n         \u003cli\u003eValve Type: Presta 40mm\u003c\/li\u003e\n         \u003cli\u003eModel: SV21\u003c\/li\u003e\n         \u003cli\u003eGenuine Schwalbe product\u003c\/li\u003e\n         \u003cli\u003ePrice is for 2 inner tubes\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n","brand":"AusPower Australia","offers":[{"title":"Default Title","offer_id":41982234886324,"sku":"B07D6LJWPR","price":172.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/products\/B07D6LJWPR.jpg?v=1666667871","url":"https:\/\/auspowers.com\/products\/schwalbe-sv21-650b-inner-tubes-27-5-x-1-5-2-4-40-62-584-presta-valve-2-pack","provider":"AusPower Australia","version":"1.0","type":"link"}
