Michelin A3 Air Comp Tube

The Michelin A3 Air Comp is designed for 700C wheels and is compatible with tire widths ranging from 26mm to 32mm. Please check your tire sidewall to confirm your current width falls within this range.

These tubes are approximately 25% lighter than standard butyl tubes, weighing in at 90 grams each. While the weight savings per wheel are modest, reducing rotational mass can provide a noticeable improvement in acceleration and handling during high-performance rides.

While they are optimized for racing, they are constructed from high-quality butyl rubber, which offers a reliable balance of elasticity and air retention. They are robust enough for regular training, though they are thinner than heavy-duty commuter tubes, so they prioritize weight savings over maximum puncture protection.

Yes, the valve core is removable, which allows you to easily attach valve extenders. This makes them compatible with a variety of rim depths beyond the standard 48mm valve length.

These tubes use a Presta valve, which is the standard narrow valve found on almost all modern road bikes. You will need a pump compatible with Presta valves.
