Ultralight TPU Bicycle Inner Tube 700×23C–32C with 45 mm French Valve for Road and Fitness Bikes 71 cm
This ultralight bicycle inner tube made from thermoplastic polyurethane (TPU) is designed for road and fitness bikes with a diameter of 71 cm (700C) and a tyre width of 2.3–3.2 cm (23–32C). Thanks to the modern TPU material, it offers significantly lower weight, higher durability, and longer lifespan than standard rubber inner tubes.
The TPU material is flexible, strong, and more resistant to punctures. It maintains pressure for a longer period and simultaneously reduces rolling resistance, thereby increasing pedalling efficiency and ride comfort. The lightweight construction helps to reduce the rotational weight of the bike, which will be appreciated by any cyclist seeking performance and energy savings.
The inner tube is equipped with a 45 mm French valve (Presta), suitable for standard road rims. The valve allows for precise inflation, seals reliably, and is easy to operate.

Before installation, slightly inflate the tube (about 0.5 bar) to ensure it settles evenly in the tyre. Do not inflate it outside the bike – this could lead to deformation or bursting. It is recommended to use a hand pump, not a compressor.
This inner tube is ideal for all cyclists who want low weight, reliability, and comfort while riding. Suitable for daily use and sporting performance.
