Michelin Aircomp A1 latex inner tube for tyre widths of 22–23 mm, 700C 28-inch, with a 60 mm valve.
Michelin latex inner tubes are not only extremely lightweight, but also reduce rolling resistance and minimise the risk of punctures. It’s a wonder everyone doesn’t use them. The pros all use latex inner tubes, either in clincher tyres or in the Michelin Pro 3 Race. The only downside – and there has to be one – is that the inner tubes only hold their air pressure for around 18–20 hours. But that’s no problem, as you naturally check your tyre pressure before every training session or race.
