EFT Inner Tube

REMARK:
A.Do not pump/test the tube in the absence of outer tire.
    Excessive pumping will result in deformation of the inner tube.
B.FOSS inner tube can be also used on carbon disk brake rim and aluminum alloy rim.
   

Our EFT is a highly polymerized un-vulcanized rubber composite. When punctured, the material forms an air-tight seal around the nail or glass, retarding the leak speed, giving riders extra time to react.

With a density of only 0.88 g/cc,our EFT is 30% lighter than traditional tubes which can have densities up to 1.3 g/cc.

Made from environmentally friendly rubber composite, FOSS tube can be recycled with other products. No poisonous gas when burned.
