Michelin Aircomp A1 Ultralight Butyl A1 700x18-23mm road bike inner tube

The Michelin AirComp Ultralight inner tube is lighter than a standard model, resulting in improved performance. What’s more, reducing weight on the bike’s rotating parts guarantees a gain in terms of watts! With this product, you’ll kill two birds with one stone by increasing both your puncture resistance and your performance. Made from butyl, this inner tube is available with three different valve lengths to suit all needs.
