Schwalbe Air Plus 17AP Tube — 700 × 35–47c, Presta 40 mm, (270 g)

The Schwalbe Air Plus 17AP inner tube is designed for 700c all-road and endurance bikes, fitting tire widths from 35–47c (ETRTO 37-622 to 47-622). Built with extra-thick Air Plus butyl rubber, this tube delivers noticeably better air retention and improved puncture resistance compared to standard tubes—meaning fewer pressure top-offs and fewer ride-ending flats. A 40 mm Presta valve with removable core ensures compatibility with modern road and gravel rims and allows easy service or sealant use if desired. Weighing approximately 270 g, it prioritizes durability and reliability over minimal weight savings, making it an excellent choice for all-road, endurance road, light gravel, commuting, and everyday riding.
