Thermoplastic polyurethane – the new material for bicycle tubes

The well-known products are being replaced by TPU inner tubes, as TPU offers many advantages over black rubber inner tubes. But what exactly is TPU? Thermoplastics are plastics that deform when heated and solidify when cooled. This property makes them ideal for manufacturing bicycle inner tubes, as they can easily adapt to any tire size and width. Furthermore, TPU inner tubes can be customized in countless ways. Depending on your needs, they can be made with multiple layers, equipped with varying levels of puncture protection, and produced in any color—the TPU inner tube is a true all-rounder.

Are road bike TPU inner tubes better than classic butyl bicycle inner tubes?

Definitely. TPU inner tubes are significantly lighter than butyl inner tubes. While a road bike tire made from the traditional material weighs around 120 grams, a comparably wide TPU inner tube weighs between 25 and 40 grams (including the valve). By the way, even when compared to a tubeless system using between 30 and 60 milliliters of tire sealant plus a valve, the TPU inner tube comes out on top in terms of weight. But TPU inner tubes aren’t just lighter; they also cause less friction against the casing of the road bike tire, resulting in better rolling performance—whether on the road or on gravel. TPU inner tubes offer additional advantages in terms of puncture resistance, pack size, and sustainability.
