The Sunlite 20in Thorn Resistant Schrader Tube is built for BMX, kids bikes, utility bikes, and 20 inch wheel setups that need added puncture protection. The 4.3mm thorn-resistant wall helps defend against flats caused by thorns, glass, debris, and rough riding conditions.
These tubes use smooth 32mm Schrader valves with removable cores and fit ISO 406 tire applications. Choose the correct variant based on your tire width range.
