Material Science & Innovation

Austrian TPU Engineering vs. Traditional Butyl Rubber

Originally derived from research into durable smartphone speaker membranes, co-founders Christian Lembacher and Akos Kertesz applied thermoplastic polyurethane (TPU) technology to reinvent the bicycle inner tube.

Through high-precision thermal welding and custom seamless extrusion techniques, Tubolito TPU gravel tubes provide unmatched durability and weight reduction for worldwide cycling procurement.

  • Sealant Resistance: Fully resistant to tubeless liquid sealant residues inside tire casings.
  • Versatile Compatibility: Fits both 700C and 650B (27.5") wheel sizes across 32mm to 50mm widths.
  • Reduced Rolling Resistance: Enhances speed and energy efficiency during long gravel races.
  • Traceable Quality: Each unit features printed product and batch codes for strict quality assurance.

Technical FAQ

Frequently Asked Questions

What are the key advantages of TPU gravel inner tubes over standard butyl tubes?
TPU (Thermoplastic Polyurethane) gravel inner tubes provide up to 80% weight reduction (weighing as low as 35g), twice the puncture resistance against snakebites and thorn punctures, significantly lower rolling resistance, and an ultra-compact size that fits effortlessly into jersey pockets or small saddle bags.
Are Tubolito gravel TPU inner tubes compatible with tubeless sealant residues?
Yes. Tubolito TPU gravel inner tubes are engineered to be fully resistant to liquid tubeless sealant residues inside tire casings, making them an excellent lightweight spare tube for tubeless gravel setups.
Can S-Tubo Gravel inner tubes be used with rim brakes?
No. The ultra-light S-Tubo Gravel features reduced wall thickness designed for minimal weight and rolling resistance. It is strictly approved for disc-brake gravel setups to avoid thermal damage from rim brake heat buildup.
How are TPU gravel tubes repaired in case of a puncture?
TPU inner tubes can be repaired quickly using the dedicated Tubo-Patch Kit formulated specifically for thermoplastic polyurethane. Standard rubber vulcanizing patches and traditional glue do not bond reliably with TPU.
What is the maximum pressure recommendation outside the tire?
Tubolito tubes must not be inflated to more than 0.5 bar (7 psi) when outside the tire casing. Inflating beyond this pressure outside the tire can cause irreversible material deformation.
