Schwalbe AV7C Extra Light

"The Schwalbe EXTRA LIGHT inner tube Nr. 7C is the perfect choice for anyone looking for a lightweight yet reliable tube for their 20inchbikes. With an ETRTO-Mau00u00df of 40/60-406, this inner tube offers the ideal fit for a wide range of bicycle tires. Despite its reduced weight, the tube loses none of the proven reliability you would expect from a Schwalbe standard tube."
"The lower weight not only reduces the overall mass of the bike, but also improves the riding dynamics. This is particularly advantageous for sporty riders and anyone who values agile handling. The EXTRA LIGHT tube is therefore the optimal addition for a fast and efficient riding experience"
"Schwalbe is known for its high-quality bicycle components, and the EXTRA LIGHT tube is no exception. It combines the manufacturer's advanced technologies and decades of experience to ensure a long service life and high puncture resistance."
