This product’s description has been automatically translated. Please excuse any mistakes.
The Airstop-Butyl hoses from the French traditional manufacturer Michelin offer tested and reliable quality in all size variants. The hose is permanently airtight and offers very good puncture resistance at a fair price/performance ratio.
The Michelin Airstop A1 tube with French racing valve (slaveand valve) is ideal for classic 28 inch racing bike tyres up to 25 mm width (ETRTO 18-25/622). For rims with a flat cross-section, choose the variant with a 40 mm long valve. For high profile rims with aero profile, the variant with a 52 mm long valve is more suitable.
