The Sunlite 20in Standard Schrader Tube is a replacement tube for 20 inch bicycle tires, including BMX, kids bikes, folding bikes, and small-wheel utility bikes. These tubes use smooth Schrader valves, removable valve cores, and 0.9mm wall thickness.
This group includes both ISO 451 and ISO 406 sizes, so customers should match the exact tire size before purchase. Available options include narrow 20 inch sizes, standard BMX-width sizes, and wider 20 x 2.75–3.00 applications.
