Sunlite Innertube
Best replacement tube for 20-inch road or folding bike tires.
This 20-inch tube is a reliable workhorse for smaller wheels, offering a straightforward, no-nonsense design. The removable Presta valve core is a thoughtful touch that makes adding sealant or extending the stem easy, though you’ll need to ensure your pump head is compatible with the shorter 32mm length.
