Michelin Airstop Tube Presta Valve

The Michelin AirStop Inner Tube is a butyl rubber inner tube designed to retain air pressure better than traditional bicycle inner tubes. Tighter control over the seam construction, better seals on the valve, and a medium tube wall thickness improves air retention and flat prevention compared to many lightweight tubes. Last but not least, there are multiple widths available to make it easier to get the right tube for your tire size/application.
