Do road shops sell inner tubes?

Sell. Inner tube, commonly known as inner tube, refers to an annular elastic tube with a tire valve, which is used to maintain the internal pressure of tire. Road bicycle shops mainly deal in road bicycles, folding bicycles and bicycle spare parts. Inner tubes belong to bicycle spare parts, so expressway stores sell inner tubes.

The inner tube should have good air tightness, heat resistance, elasticity, aging resistance and small permanent deformation. Generally made of butyl rubber.
