Foss Inner Tubes

FOSS inner tube Product Features Explosion Proof : 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. High Elasticity : FOSS tube provides a superior ride quality due to high elasticity of the material which can actually reduce the rolling resistance. Light-Weight & Environmentally Friendly Material : The material density is 0.88 g/cc. It is 30% lighter than traditional tubes (of the same thickness). Made from recycled Environmentally Friendly material.
