Michelin AirStop Butyl Tube
One of the best Butyl inner tubes available that offers excellent puncture resistance and the consistently high quality for which Michelin is famous.Unlike many other manufacturers, Michelin AirStop Butyl Tube uses a very high level of butyl in the compound of their tubes for improved reliability, virtually eliminating any air leakage. Lighter tubes are available but manufacturers achieve this by using less butyl, which can leak air, or a thinner tube that is more prone to punctures.
