Take your ride to the next level with the ROAD 38g TPU Inner Tube, engineered for cyclists who demand maximum performance with minimal weight. Designed for road bikes, mountain bikes, and cruisers, this next-generation TPU tube delivers exceptional toughness in an incredibly lightweight and compact design.

Constructed from special high-performance TPU material, this inner tube weighs just about 38g, dramatically reducing rotating mass compared to traditional butyl tubes. The result is quicker acceleration, improved efficiency, and a more responsive ride—perfect for training, racing, or long-distance road cycling.

Equipped with a precision aluminum alloy Presta valve, available in 45mm, 60mm, or 80mm, the tube is compatible with a wide range of rim depths. Its small packed size makes it ideal as a saddle-bag spare, while the pale green color allows for quick identification during installation or roadside repairs.
