Tubo Technology Platform

Tubo technology represents our core engineered elastomer formulation. By utilizing a high-molecular thermoplastic polymer, Tubo inner tubes eliminate the inherent bulk and degradation of conventional butyl rubber while maintaining outstanding air retention.

Key Engineering Advantages:

  • Durable Construction: Twice as puncture-resistant in standardized needle penetration tests.
  • Rotating Mass Reduction: 2/3 lighter than standard rubber tubes for improved acceleration.
  • Long-Term Reliability: Highly resistant to thermal oxidation, ozone damage, and aging.
  • Discipline Compatibility: Configured for Road, MTB, Gravel, Cyclocross, BMX, and Cargo bikes.
Ultralight Competition Spec

S-Tubo Technology Platform

S-Tubo (Super-Tubo) was developed for competitive racing discipline and emergency spare compactness. By extruding an ultra-thin TPU wall without compromising seam integrity, S-Tubo delivers rolling resistance profiles comparable to latex tubes while packing down to a micro pocket size.

Key Engineering Advantages:

  • Featherweight Efficiency: Up to 80% lighter than standard rubber inner tubes (Road from 23g).
  • Extreme Compactness: Fits effortlessly into jersey pockets, saddle bags, or storage capsules.
  • Minimal Friction Loss: Lower hysteresis loss for maximum wattage conversion on tarmac and trail.
  • Removable Valve Stems: Allows ultra-small packing dimensions and easy valve extension setup.

Maximum Flat Protection

X-Tubo Technology Platform

Engineered to eliminate flat tires in demanding daily urban commutes, e-bike fleets, and touring conditions. X-Tubo features a specially reinforced TPU wall composite that withstands thorn punctures, glass cuts, and pinch flats far beyond standard commercial tubes.

Key Engineering Advantages:

  • Zero-Flat Architecture: Withstands severe puncture tests from sharp nails and thorns.
  • E-Bike Approved: Formulated for high torque, heavy system mass, and aggressive urban debris.
  • 1-Year Manufacturer Warranty: Supported by Tubolito's replacement policy for registered X-Tubos.
  • Seamless Extrusion: High tensile weld points prevent sudden blowouts under load.
Connected Cycling Telemetry

SYNCD Smart Pressure Sensing

Tubo-Road SYNCD incorporates a miniature, battery-powered Bluetooth pressure sensor seamlessly inside the TPU inner tube structure. SYNCD streams continuous, real-time pressure metrics directly to cycling head units and mobile applications without adding rotational imbalance.

Key Engineering Advantages:

  • Real-Time Monitoring: Transmits precise PSI / Bar live telemetry directly while riding.
  • Universal Wireless Protocol: Connects natively to Garmin computers, iOS, and Android apps.
  • Safety Threshold Warnings: Configurable low-pressure and rapid-leak alert notifications.
  • Zero Air Leak Sensor: Internal integration requires no external valve attachment adapters.

OEM Quality Assurance

Patented Manufacturing & Batch Traceability

Unlike standard rubber inner tubes produced via heat vulcanization, Tubolito utilizes high-precision laser-welded thermoplastic extrusion. Every single inner tube manufactured in Austria undergoes 100% automated pressure retention quality checks prior to distribution.

Industrial OEM Traceability Standard

  • 9-Digit Product Identification: Permanently laser-marked adjacent to the valve stem for accurate specification verifying.
  • Batch Traceability Code: 4 to 5-digit batch identifier ensuring full production lot transparency from raw TPU pellet sourcing to final assembly.
  • Logistics Efficiency: Compact packing geometry cuts container shipping volumes by up to 70% compared to bulky butyl tubes.

Frequently Asked Questions on TPU Engineering

What is the technical difference between Tubo, S-Tubo, and X-Tubo?
Tubo is our versatile everyday performance tube that reduces weight by 2/3 while doubling puncture resistance compared to butyl. S-Tubo features an ultra-thin wall construction saving up to 80% weight, making it the lightest spare and racing tube available. X-Tubo uses a heavy-duty reinforced TPU formulation designed for zero-flat urban commuting, cargo bikes, and e-bikes.
How to calculate the correct Presta valve length for deep rim profiles?
Standard pump heads require at least 15 mm of exposed valve length above the rim bed. Calculate minimum valve length using the equation: Valve Length (mm) - Rim Depth (mm) ≥ 15 mm. Tubolito provides valve options from 42mm up to 80mm.
What are the inflation pressure constraints for TPU inner tubes?
When installed inside a mounted tire, Tubolito TPU tubes safely support the maximum inflation pressure printed on the tire sidewall. Critical Safety Rule: Never inflate a Tubolito TPU inner tube above 0.5 Bar (7 PSI) outside of the tire casing, as unconstrained inflation will permanently deform the TPU wall.
How does TPU rolling resistance perform in independent testing?
Independent laboratory tests show that Tubolito S-Tubo models deliver rolling resistance nearly identical to latex tubes, while dramatically outperforming standard butyl tubes in speed and maintaining long-term air retention.
Can Tubolito TPU tubes be vulcanized or patched?
TPU tubes cannot be repaired with standard vulcanizing rubber glue used for butyl rubber. They must be repaired using dedicated self-adhesive TPU patches (such as the Tubo-Patch Kit), which form an airtight molecular bond with thermoplastic polyurethane.
