Schwalbe Aerothan Gravel/Allroad 700x33-47 inner tube

Schwalbe Aerothan Inner Tube Gravel/Allroad: Innovation in Thermoplastic Polyurethane

The Aerothan inner tube represents a significant advancement in the bicycle inner tube sector for gravel and allroad bikes. Manufactured 100% from TPU (thermoplastic polyurethane), this solution delivers superior performance compared to traditional butyl tubes. The innovative material ensures a 40% weight reduction compared to Schwalbe Extralight butyl tubes of the same category, while maintaining a markedly higher puncture resistance. Its fully recyclable structure makes it a conscientious choice for those seeking sustainability without compromising performance. Thanks to its compact size and ease of installation, this inner tube is perfectly suited for riders using gravel, road, or allround bicycles, offering an ideal balance between lightness and reliability.

Rolling Performance and Puncture Protection

The rolling resistance of the Aerothan tube is comparable to tubeless systems, ensuring energy efficiency during pedaling. This technical feature is particularly relevant for those engaged in cycle touring on mixed terrains or competing on gravel. Puncture protection has been enhanced through a TPU formulation combining elasticity and durability, significantly reducing the risk of accidental punctures. The Aerothan-Plus inner tube is a variant with increased wall thickness, providing 80% additional puncture resistance compared to the standard version, ideal for riders tackling especially demanding routes or terrains with thorny vegetation.

Technical Specifications and Compatibility for gravel Bicycles

The reviewed version measures 700x33/47, a versatile size compatible with numerous gravel and allroad tires available on the market. Weighing only 61 grams, this inner tube minimally contributes to the overall bicycle weight, a crucial factor for those seeking lightness without sacrificing durability. The valve, also made of TPU, has a length of 80mm, compatible with standard rims and medium-high profiles. The product code SCV 17-AE identifies this specific configuration. The TPU technology used for the entire construction, including the valve, ensures material consistency and long-term reliability, eliminating compatibility issues between different components.
