The Sunlite 20in Standard Presta Tube covers common 20 inch bicycle tire sizes for BMX, recumbent, folding, and small-wheel bike applications. Each tube uses a 0.9mm wall thickness with a removable-core Presta valve.
This group includes both ISO 451 and ISO 406 sizes, so customers should match the exact tire size and ISO marking before purchase. Available options include narrow 20 x 1 road-style sizes and wider 20 x 1.25–1.50 fitments.
