ELASTIC BUTYL RUBBER - We also accept no compromise when it comes to material quality. This is why our tube is made of an elastic and at the same time airtight butyl rubber. Due to the high air holding capacity, hardly any air pressure is lost, which minimizes the wear on the tyre. SCHRADER VALVE - Our tube's first-class Schrader valve (Auto valve) ensures high air tightness and easy inflation. It can be inflated with all common floor pumps, mini pumps, hand pumps or CO2 cartridge pumps. MOBILITY COMMITMENT - We stand by our bike tubes for one year. If a tube has a defect or leak, we’ll replace it at no cost to you! This excludes damage from external causes like glass, nails, chips, or snake bites. Product packaging may vary.
