The new FOSS EFT tube system is being produced from a thermoplastic elastomer compound, which not only makes it especially lightweight but also puncture-proof.

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 modified thermoplastic elastomer compounds(TPE),our EFT can be recycled with other TPE products,thus minimizing waste and protecting the environment.
