Foss 700 x 28C-38C Inner Tube

FOSS inner tube Product Features

When pierced, the highly-polymerized material of the tube will create an air-tight seal around the object and prevent an immediate puncture which fully gives the riders more time to react.

FOSS tube provides a superior ride quality due to high elasticity of the material which can actually reduce the rolling resistance.

The material density is 0.88 g/cc. It is 30% lighter than traditional tubes (of the same thickness).
And it is a recycled Environmentally Friendly material.
