For the racers among gravel bikers – super light, super fast

Cross and gravel bike riders are out there riding hard on the trails. But not all hard riding is the same. Those who race on gravel need a fast setup combined with high puncture protection. Cross racers, who are allowed to change bicycles after every round during competition, choose the SuperLite Race for maximum performance with the same puncture protection offered by conventional butyl inner tubes.

Thermoplastic polyurethane – the new material for bicycle tubes

The familiar 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, a true all-rounder.

Are TPU inner tubes better for gravel bikes than butyl bicycle inner tubes?

Absolutely: Yes! TPU inner tubes offer comparable handling, but they roll better, are lighter, have a smaller pack size, and are significantly more puncture-resistant than butyl inner tubes. To put it plainly: TPU inner tubes have nothing but advantages over butyl inner tubes. The only downside is that they are more expensive to purchase, but this is significantly offset by all the benefits.
