Butyl is a highly elastic yet airtight synthetic rubber. Before extrusion, the base material is forced through seven filters under enormous pressure. All tubes are then placed in a mold and inflated for vulcanization. This is the only way to guarantee consistent wall thickness and excellent air retention. All finished tubes are inflated and stored for at least 24 hours to test their air retention. Afterward, each tube undergoes a thorough visual inspection. For many years, German bicycle retailers have valued Schwalbe inner tubes for their exceptional reliability. Every Schwalbe inner tube is 100% recyclable. Schwalbe can use recycled butyl rubber in the production of new tubes without any loss of quality. Therefore, every new standard Schwalbe inner tube already consists of approximately 20% recycled material. This process consumes only one-fifth of the energy required to produce the same amount of new butyl rubber.<\/p>\n<\/div>\n<\/div>\n<div data-role=\"highlight\">\n<h3>Highlights<\/h3>\n<div data-colname=\"de_highlights\">\n<ul>\n<li>reliability<\/li>\n<li>High air retention<\/li>\n<li>Uniform wall thicknesses<\/li>\n<li>Material: Butyl rubber<\/li>\n<li>100 percent recyclable<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<div data-role=\"tech\">\n<h3>Technologies used<\/h3>\n<p>In this chapter, we explain the technologies that the manufacturer uses in this product.<\/p>\n<div data-colname=\"de_technology\">\n<p><b>car valve<\/b><br \/>\nThe car valve can be filled very easily at the petrol station.<\/p>\n<p><b>Sclaverand valve<\/b><br \/>\nThe Sclaverand valve is narrower than other valves (6 mm instead of 8 mm). It requires a smaller rim hole and is therefore particularly well-suited for narrow road bike rims. It has also become established on many mountain bikes.<\/p>\n<p><b>Dunlop valve<\/b><br \/>\nThe classic bicycle valve, or Dunlop valve, is still the most common type on city bikes. Most bikes are familiar with it. The valve core is easy to replace, and air can be released very quickly. However, fitting a tube with a Dunlop valve is more involved because the valve has to be disassembled and reassembled.<\/p>\n<\/div>\n<\/div>\n<div data-role=\"scope\">\n<h3>Scope of delivery<\/h3>\n<div data-colname=\"de_delivery\">\n<ul>\n<li>1x Schwalbe inner tube No. 20 for 28&#039;&#039; SV20 ExtraLight (700\/18-25C) French valve 65g (see item description for details)<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<table class=\"hibike-specs\">\n<tr>\n<th>brand<\/th>\n<td>swallow<\/td>\n<\/tr>\n<tr>\n<th>EAN<\/th>\n<td>4026495099721<\/td>\n<\/tr>\n<tr>\n<th>Myeloproliferative Neoplasm<\/th>\n<td>10426343<\/td>\n<\/tr>\n<tr>\n<th>Wheel size<\/th>\n<td>28&quot; (622 mm) inch<\/td>\n<\/tr>\n<tr>\n<th>Valve length<\/th>\n<td>20 mm<\/td>\n<\/tr>\n<tr>\n<th>Valve type<\/th>\n<td>SV<\/td>\n<\/tr>\n<\/table>","protected":false},"excerpt":{"rendered":"<p>Schwalbe ExtraLight Schlauch Nr. 20 f&uuml;r 28&#039;&#039; SV20 (700\/18-25C) Dieser Schlauch zeichnet sich durch sein geringes Gewicht aus.
