Eclipse inner tubes are built from Thermoplastic Polyurethane (TPU) — an advanced material that bridges the gap between rubber and plastic, delivering the best of both worlds: the flexibility of an elastomer with the durability of a high-performance polymer.
Incredibly Light. Remarkably Strong.
TPU has been trusted in high-performance sports equipment for decades — and for good reason. Eclipse TPU stretches over 400% before failing, allowing us to engineer tubes that are thinner and lighter than traditional options, without compromising on puncture resistance or ride reliability. Whether you're climbing, sprinting, or navigating rough terrain, Eclipse tubes are built to handle it.
Sustainable by Design
TPU isn't just better for your bike — it's better for the planet. Unlike conventional rubber tubes, TPU can be fully recycled and reprocessed without losing its core material properties. Choosing Eclipse means choosing a component that performs today and contributes to a more sustainable future for cycling.
