Highlights

  • PUNCTURE PROTECTION

    Due to high elasticity and material strength, AERON/TPU Airtubes have extremely high puncture protection.

    Puncture safety is tested in the laboratory

  • LOWER ROLLING RESISTANCE

    AERON/TPU Airtubes absorb less energy, which significantly reduces rolling resistance.

    Rolling resistance in the laboratory test

  • LOWER WEIGHT

    AERON/TPU Airtubes are on average two thirds lighter than comparable butyl bicycle tubes.

    Inflated AERON/TPU tube

  • SMALL PACKING SIZE

    AERON/TPU Airtubes can be rolled up tightly into an incredibly compact size.
